The power gauge (230) can measure usage status information for the battery (189) (e.g., capacity, number of charge / discharge cycles, voltage, or temperature of the battery (189).
[0060] The power management module (188) can determine charging state information (e.g., lifespan, overvoltage, undervoltage, overcurrent, overcharge, overdischarge, overheat, short circuit, or swelling) related to charging of the battery (189) based at least in part on the measured usage state information, for example, using the charging circuit (210), the power regulator (220), or the power gauge (230). The power management module (188) can determine whether the battery (189) is normal or abnormal based at least in part on the determined charging state information. If the state of the battery (189) is determined to be abnormal, the power management module (188) can adjust charging of the battery (189) (e.g., reducing the charging current or voltage, or stopping charging). According to one embodiment, at least some of the functions of the power management module (188) can be performed by an external control device (e.g., the processor (120)).
[0061] The battery (189) may include, for example, a battery (189) protection circuit module (PCM) (240). The battery (189) protection circuit (240) may perform one or more of various functions (e.g., a pre-cut function) to prevent performance degradation or damage of the battery (189). The battery (189) protection circuit (240) may additionally or alternatively be configured as at least a part of a battery (189) management system (340) (battery management system (BMS)) that may perform various functions including cell balancing, capacity measurement of the battery (189), charge / discharge cycle measurement, temperature measurement, or voltage measurement.
[0062] According to one embodiment, at least a portion of the usage status information or the charging status information of the battery (189) may be measured using a corresponding sensor (e.g., a temperature sensor) among the sensor modules (276), a power gauge (230), or a power management module (188). According to one embodiment, the corresponding sensor (e.g., a temperature sensor) among the sensor modules (176) may be included as part of a battery (189) protection circuit (240), or may be placed near the battery (189) as a separate device.
[0063] FIG. 3 is a block diagram of an electronic device (101) including a charging circuit (210) according to one embodiment.
[0064] Referring to FIG. 3, an electronic device (e.g., electronic device (101) of FIG. 1) according to one embodiment may include a battery (e.g., battery (189) of FIG. 1), a charging circuit for charging the battery (189) (e.g., charging circuit (210) of FIG. 2), a processor (e.g., processor (120) of FIG. 1) electrically connected to the charging circuit (210), and a system (340).
[0065] According to one embodiment, the charging circuit (210) may include a first charger (310) and a second charger (320). The first charger (310) and the second charger (320) may be electrically connected to an external device (301) via a designated interface.
[0066] The external device (301) may be a power supply device, for example, a charger (e.g., a power adapter). The term "external device (301)" may be used interchangeably with terms such as "external power source," "external electronic device," "wired charger," "wireless charger," or "charger."
[0067] The external device (301) and the charging circuit (210) may be electrically connected through a designated interface. The designated interface may include, for example, a pogo pin interface or a USB interface. The USB interface may be connected to the external device (301) through a USB C type CC terminal (not shown), and may perform a type C detection function for checking the Rp value through the CC terminal, PD BMC (bi-phase marked code) communication, or PPS (programmable power supply) communication. For example, among the pins of the USB Type-C socket, the VBUS pin may be used as a power terminal, and the CC (configuration channel) pin and / or differential signal pin (e.g., DP (D+), DN (D-)) may be used as a data terminal. According to one embodiment, the external device (301) and the charging circuit (210) may be electrically connected through a wireless interface.
[0068] According to one embodiment, when an external device (301) is connected, the processor (120) can check the type of the external device (301). The type of the external device (301) may refer to the type of the range of power (or maximum output power) that the external device (301) can output. For example, the type of the external device (301) may refer to the range of voltage of power that the external device (301) can output, or the range of current of power that the external device (301) can output.
[0069] According to one embodiment, the processor (120) can determine whether the connected external device (301) is a PPS charger capable of varying output current and output voltage. The PPS charger can adjust the output voltage in a range of about 3 V to about 21 V based on the control of the electronic device (101). The PPS charger can supply an output voltage in a specified range to an electronic device (101) that supports direct charging (hereinafter, “DC charging”) using a switched cap (capacitor) divider method, wherein the output voltage in the specified range can be in a range of about 3 V to about 21 V. The PPS charger can adjust the output voltage in a range of about 3 V to about 21 V and supply the adjusted output voltage to the electronic device (101). In the present disclosure, “charger” may mean “charger that supports a function.”
[0070] According to one embodiment, the processor (120) may electrically connect the external device (301) and the second charger (320) if the connected external device (301) is a PPS charger. The processor (120) may charge the battery (189) using the second charger (320) and supply load power to the system (340).
[0071] According to one embodiment, the processor (120) may electrically connect the external device (301) to the first charger (310) if the connected external device (301) is not a PPS charger. The processor (120) may charge the battery (189) using the first charger (310) and supply load power to the system (340). The non-PPS charger may include, for example, a charger that provides a fixed output voltage of about 9 V and / or about 5 V (e.g., a “first charger” hereinafter), a charger that can provide an output voltage between about 3.5 V and about 22 V (e.g., a “second charger” hereinafter), or a charger that provides a fixed output voltage of about 5 V (e.g., a “third charger” hereinafter). The non-PPS charger may include, for example, a charger whose maximum output power is less than about 45 W and greater than or equal to about 25 W. Non-PPS chargers may include, for example, chargers having a maximum output power of less than about 25W and greater than or equal to about 15W.
[0072] According to one embodiment, the first charger (310) may include a switching charger (or switching regulator) including a buck-boost converter (not shown) and a charge controller (not shown). The first charger (310) may charge the battery (189) by adjusting an input voltage or input current input from an external device (301) via a USB interface (310).
[0073] In one embodiment, the first charger (310) may be a component integrated into an interface-integrated (IF) power management integrated circuit (PMIC). In one embodiment, the first charger (310) may include an inductor (311) and / or a semiconductor device (e.g., a metal-oxide-semiconductor field effect transistor (MOSFET)).
[0074] According to one embodiment, the second charger (320) may be a direct charger that supports direct charging (hereinafter, “DC charging”) using a switched cap (capacitor) divider method. According to one embodiment, the second charger (320) may include a power converter that lowers an input voltage input from an external device (301) by a specified ratio and outputs it, and increases an input current input from the external device (301) by the specified ratio and outputs it. According to one embodiment, the second charger (320) may include a capacitor (321) and / or a semiconductor device (e.g., a metal-oxide-semiconductor field effect transistor (MOSFET)). According to one embodiment, the second charger (320) may include a switched capacitor converter.
[0075] In one embodiment, the second charger (320) may include a 2:1 voltage divider that reduces the input voltage by half and increases the input current by two times. In various embodiments, the second charger (320) is not limited to including a 2:1 voltage divider, but may be variously designed to include a 3:1 voltage divider that reduces the input voltage by one-third and increases the input current by three times, or a 4:1 voltage divider that reduces the input voltage by one-quarter and increases the input current by four times. In the present disclosure, the output voltage of the second charger (320) is defined as the VSYS voltage. For example, the VSYS voltage, which is the output voltage of the second charger (320), may mean a voltage supplied from the second charger (320) to the system (340) of the electronic device (101) (e.g., loads (351, 352)).
[0076] According to one embodiment, an overvoltage protection circuit, an OVP (overvoltage protection) IC (330), may be placed in a path along which an external device (301) and a first charger (310) are electrically connected. The OVP IC (330) serves to protect each component of an electronic device (101) including the first charger (310) when the "VBUS voltage", which is a voltage output from the external device (301), abnormally increases.
[0077] According to one embodiment, the term "system (340)" may be used interchangeably with terms such as "load." The system (340) may be interpreted as including a plurality of components (e.g., a first load (351), a second load (352)) or a plurality of elements included in the electronic device (101). The system (340) of the electronic device (101) may include, as loads, the elements of the electronic device (101) described with reference to FIG. 1, and may include, for example, at least some of a processor (120), a memory (130), an input module (150), an audio output module (155), a display module (160), an audio module (170), a sensor module (176), an interface (177), a connection terminal (178), a haptic module (179), a camera module (180), a power management module (188), a battery (189), a communication module (190), a subscriber identification module (196), or an antenna module (197). The system (340) may include a plurality of individual power supplies (341, 342) for supplying individually designated voltages to respective components (e.g., first load (351), second load (352)) (i.e., components) of the electronic device (101). The plurality of individual power supplies (341, 342) may include a switching charger (or a switching regulator) and may be implemented as at least a part of a PMIC. The plurality of individual power supplies (341, 342) may receive a VSYS voltage from the first charger (310) or the second charger (320), convert the input VSYS voltage into a designated voltage corresponding to each component (e.g., first load (351), second load (352)), and supply the converted voltage to each component (e.g., first load (351), second load (352)).
[0078] In FIG. 3, the first load (351) (or first load circuit), the first power supply unit (341) supplying a specified voltage to the first load (351), the second load (352) (or second load circuit), and the second power supply unit (342) supplying a specified voltage to the second load (352) are exemplarily described as internal components of the system (340), but the present disclosure is not limited thereto. In the embodiment of FIG. 3, the first load (351) may be any one of the components of the electronic device (101) described with reference to FIG. 1, for example, the display module (160), but the present disclosure is not limited thereto. In the embodiment of FIG. 3, the second load (352) may be any other one of the components of the electronic device (101) described with reference to FIG. 1, for example, the camera module (180), but the present disclosure is not limited thereto. In addition to the first load (351) and the second load (352), the system (340) may further include additional loads. The system (340) may further include power supply devices for supplying individually designated voltages to the additional loads.
[0079] Figure 4 is a graph (400) showing the efficiency measurement of a second charger (320) according to one embodiment.
[0080] The efficiency of a second charger (e.g., the second charger (320) of FIG. 3) may be an indicator of the degree of loss in output power output from the second charger (320) relative to the input power input to the second charger (320). For example, if the power loss in the second charger (320) is relatively small, the efficiency of the second charger (320) may be measured as high. If the power loss in the second charger (320) is relatively large, the efficiency of the second charger (320) may be measured as low.
[0081] In Fig. 4, the horizontal axis represents the load current output from the second charger (320) and supplied to the system (e.g., the system (340) of Fig. 3). In Fig. 4, a section corresponding to the horizontal axis with a large load current (e.g., a section with a load current of about 1000 mA or more) may be defined as a high-power section, and a section in the graph of Fig. 4 with a small load current (e.g., a section with a load current of less than about 1000 mA) may be defined as a low-power section.
[0082] In FIG. 4, the vertical axis represents the efficiency of the second charger (320), and the unit may be percentage (%).
[0083] In FIG. 4, graph 401 may be a curve representing the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 3.6 V. In FIG. 4, graph 402 may be a curve representing the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 3.8 V. In FIG. 4, graph 403 may be a curve representing the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 4.0 V. In FIG. 4, graph 404 may be a curve representing the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 4.2 V. In FIG. 4, graph 405 may be a curve representing the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 4.4 V.
[0084] Referring to FIG. 4, it can be seen that in a low-power section where the load current is small (e.g., a section where the load current is less than about 1000 mA), the change in efficiency according to the change in the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is relatively small. For example, in a low-power section, the difference between the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 3.6 V and the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 4.4 V is relatively small.
[0085] Referring to FIG. 4, it can be seen that in a high-power section where the load current is large (e.g., a section where the load current is about 1000 mA or more), the change in efficiency according to the change in the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is relatively large. For example, in a high-power section, the difference between the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 3.6 V and the efficiency of the second charger (320) when the output voltage (e.g., VSYS of FIG. 3) is about 4.4 V is relatively large.
[0086] According to one embodiment, an electronic device (e.g., an electronic device (101) of FIG. 1) may set an output voltage (e.g., VSYS of FIG. 3) of a second charger (320) to a first voltage that is greater than or equal to a reference voltage in a high-power section in which a load current is large (e.g., a section in which a load current is about 1000 mA or more). According to one embodiment, the electronic device (101) may increase the efficiency of the second charger (320) by setting the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) to a first voltage that is a high voltage in a high-power section in which a load current is large (e.g., a section in which a load current is about 1000 mA or more).
[0087] According to one embodiment, the electronic device (101) may set the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) to a second voltage lower than the reference voltage in a low-power section where the load current is small (e.g., a section where the load current is less than about 1000 mA). This is because, in a low-power section where the load current is small (e.g., a section where the load current is less than about 1000 mA), the change in efficiency of the second charger (320) according to the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is small.
[0088] Fig. 5 is a graph (500) measuring the efficiency of individual power supply units (341, 342) according to one embodiment. For example, Fig. 5 is a graph measuring the efficiency of the first power supply unit (341) or the efficiency of the second power supply unit (342) described with reference to Fig. 3.
[0089] The efficiency of an individual power supply (e.g., the individual power supply (341, 342) of FIG. 3) may be an indicator of the degree of loss in the output power output from the individual power supply (341, 342) with respect to the input power input to the individual power supply (341, 342) (e.g., the output voltage of the second charger (320) (e.g., VSYS of FIG. 3)). For example, if the power loss in the individual power supply (341, 342) is relatively small, the efficiency of the individual power supply (341, 342) may be measured as high. If the power loss in the individual power supply (341, 342) is relatively large, the efficiency of the individual power supply (341, 342) may be measured as low.
[0090] In FIG. 5, the horizontal axis represents the load current output from the second charger (e.g., the second charger (320) of FIG. 3) and supplied to the system (e.g., the system (340) of FIG. 3) (i.e., the individual power supplies (341, 342)). In FIG. 5, a section corresponding to the horizontal axis with a large load current (e.g., a section with a load current of about 1000 mA or more) may be defined as a high-power section, and a section in the graph of FIG. 5 with a small load current (e.g., a section with a load current of less than about 1000 mA) may be defined as a low-power section.
[0091] In FIG. 5, the vertical axis represents the efficiency of individual power supplies (341, 342), and the unit may be percentage (%).
[0092] In FIG. 5, graph 501 may be a curve representing the efficiency of individual power supplies (341, 342) when the output voltage of the second charger (320) (e.g., VSYS of FIG. 3) is about 3.3 V. In FIG. 5, graph 502 may be a curve representing the efficiency of individual power supplies (341, 342) when the output voltage of the second charger (320) (e.g., VSYS of FIG. 3) is about 5.0 V.
[0093] Referring to FIG. 5, it can be seen that in a low-power section where the load current is small (e.g., a section where the load current is less than about 1000 mA), the change in the efficiency of the individual power supplies (341, 342) according to the change in the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is relatively large. For example, in a low-power section where the load current is small (e.g., a section where the load current is less than about 1000 mA), the difference between the efficiency of the individual power supplies (341, 342) when the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is about 3.3 V and the efficiency of the individual power supplies (341, 342) when the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is about 5.0 V is relatively large.
[0094] Referring to FIG. 5, in a high-power section where the load current is large (e.g., a section where the load current is about 1000 mA or more), it can be seen that the change in the efficiency of the individual power supplies (341, 342) according to the change in the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is relatively small. For example, in a high-power section where the load current is large (e.g., a section where the load current is about 1000 mA or more), the difference between the efficiency of the individual power supplies (341, 342) when the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is about 3.3 V and the efficiency of the individual power supplies (341, 342) when the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) is about 5.0 V is relatively small.
[0095] According to one embodiment, an electronic device (e.g., electronic device (101) of FIG. 1) may set the output voltage of the second charger (320) (e.g., VSYS of FIG. 3) to a first voltage that is greater than or equal to a reference voltage in a high-power section in which the load current is large (e.g., a section in which the load current is about 1000 mA or more). This is because, in a high-power section in which the load current is large (e.g., a section in which the load current is about 1000 mA or more), the change in efficiency of individual power supplies (341, 342) according to the output voltage of the second charger (320) (e.g., VSYS of FIG. 3) is small.
[0096] According to one embodiment, the electronic device (101) can set the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) to a second voltage lower than the reference voltage in a low power section where the load current is small (e.g., a section where the load current is less than about 1000 mA). According to one embodiment, the electronic device (101) can increase the efficiency of the individual power supplies (341, 342) by setting the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) to a second voltage lower than the reference voltage in a low power section where the load current is small (e.g., a section where the load current is less than about 1000 mA).
[0097] FIG. 6 is a flowchart illustrating a method for activating a no-battery mode in an electronic device (101) according to one embodiment. FIG. 7 is a screen of a first user interface (700) for activating the no-battery mode. FIG. 8 is a screen of a second user interface (800) for activating the no-battery mode. FIG. 9 is a screen of an exemplary scenario in which a user removes a battery (189) from the electronic device (101).
[0098] The operations illustrated in FIG. 6 may be performed by instructions stored in a memory (e.g., memory (130) of FIG. 1). For example, the instructions, when executed by a processor (e.g., processor (120) of FIG. 1), may cause an electronic device (e.g., electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 6.
[0099] At least some of the operations illustrated in FIG. 6 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 6.
[0100] According to one embodiment, at least some of the operations illustrated in FIG. 6 may be performed sequentially.
[0101] According to one embodiment, at least some of the operations illustrated in FIG. 6 can be performed in parallel (simultaneously).
[0102] Hereinafter, a method for activating a no battery mode by an electronic device (101) according to one embodiment will be described with reference to FIGS. 6 to 9.
[0103] In operation 610, an electronic device (101) according to one embodiment may receive a user's designated gesture input (701) for a portion of a screen while an external device (e.g., the external device (301) of FIG. 3) is connected. For example, as illustrated in FIG. 7, the electronic device (101) may receive a drag input (701) for lowering the top of the screen as a designated gesture while displaying a screen through the display module (160).
[0104] In operation 620, the electronic device (101) according to one embodiment may display a screen of a first user interface (700) including a plurality of icons (711) in response to a user's designated gesture (701). For example, as illustrated in FIGS. 7 and 8 , the electronic device (101) may display a menu screen (710) including a plurality of icons (711) related to functions of the electronic device (101) in response to a drag input (701) that lowers the top of the screen. The example illustrated in FIG. 7 may be a first user interface (700) displayed when the electronic device (101) receives a drag input (701) that lowers the top of the screen once. The example illustrated in FIG. 8 may be a second user interface (800) displayed when the electronic device (101) receives a drag input that lowers the top of the screen twice.
[0105] Each of the plurality of icons (711) included in the first user interface (700) (or the second user interface (800)) may be objects for executing each of the functions provided by the electronic device (101). When the electronic device (101) receives a user input (801) for selecting a designated icon (711a) from among the plurality of icons (711), the electronic device (101) may execute a function mapped to the selected designated icon (711a). For example, when the icon (711) displayed on the menu screen (710) is an icon related to a Bluetooth function, the electronic device (101) may activate the Bluetooth function of the electronic device (101) in response to a user input (801) for selecting the corresponding icon (711).
[0106] Referring to FIG. 8, a plurality of icons (711) included in the first user interface (700) (or the second user interface (800)) may include a first icon (711a) for switching the electronic device (101) to a no battery mode. The no battery mode refers to a mode in which the system (340) of the electronic device (101) is driven using input power input from an external device (301) while the battery (189) is removed from the electronic device (101). In the present disclosure, the term “no battery mode” may be used interchangeably with terms such as “first state” or “first mode”.
[0107] In operation 630, the electronic device (101) according to one embodiment may receive a user input (801 of FIG. 8) for selecting a first icon (711a) related to a no battery mode (e.g., a first state) from among a plurality of icons (711) included in the first user interface (700) (or the second user interface (800)). For example, in response to the user input (801) for selecting the first icon (711a), the electronic device (101) may display the first icon (711a) by switching it from an inactive state to an active state.
[0108] In operation 640, the electronic device (101) according to one embodiment can identify the type of the external device (301) based on a user input (801) selecting the first icon (711a). For example, the electronic device (101) can identify the maximum output power of the external device (301).
[0109] In operation 650, the electronic device (101) according to one embodiment may determine whether the maximum output power of the external device (301) is less than a specified threshold. For example, the specified threshold may be about 15 W, but the present disclosure is not limited thereto. According to one embodiment, the electronic device (101) may determine whether the maximum output power of the external device (301) is less than about 15 W. The fact that the maximum output power of the external device (301) is less than the specified threshold may mean that the electronic device (101) cannot execute a no-battery mode (e.g., a first state) using the input power input from the external device (301). The electronic device (101) may check the maximum output power of the external device (301) to determine whether the no-battery mode is executable (e.g., whether a transition to the first state is possible).
[0110] The electronic device (101) may perform operation 660 when the maximum output power of the external device (301) is less than a specified threshold (e.g., the result of operation 650 is “yes”). For example, the electronic device (101) may perform operation 660 when the maximum output power of the external device (301) is less than about 15 W.
[0111] The electronic device (101) may perform operation 670 if the maximum output power of the external device (301) is greater than or equal to a specified threshold (e.g., the result of operation 650 is “No”).

When the electronic device (101) switches to the first state, the electronic device (101) may drive the system (340) of the electronic device (101) using input power input from the external device (301). To this end, the electronic device (101) may supply the input power input from the external device (301) to the second charger (320).

[0116] The operations illustrated in FIG. 10 may be performed by instructions stored in a memory (e.g., memory (130) of FIG. 1). For example, the instructions, when executed by a processor (e.g., processor (120) of FIG. 1), may cause an electronic device (e.g., electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 10.
[0117] At least some of the operations illustrated in FIG. 10 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 10.
[0118] According to one embodiment, at least some of the operations illustrated in FIG. 10 may be performed sequentially.
[0119] According to one embodiment, at least some of the operations illustrated in FIG. 10 may be performed in parallel (simultaneously).
[0120] Hereinafter, operations performed by an electronic device (101) according to one embodiment while in no battery mode will be described with reference to FIG. 10.
[0121] In operation 1010, an electronic device (101) according to one embodiment may determine whether it is in a first state (e.g., no battery mode) in which the electronic device (101) is driven by input power supplied from an external device (e.g., external device (301) of FIG. 3) while a battery (e.g., battery (189) of FIG. 1) is removed from the electronic device (101). The electronic device (101) may be transitioned to the first state by performing at least some of the operations described with reference to FIG. 6.
[0122] In operation 1020, the electronic device (101) according to one embodiment may monitor the supply power supplied by the second charger (e.g., the second charger (320) of FIG. 3) to the system (e.g., the system (340) of FIG. 3) based on determining that the electronic device (101) is in a first state (e.g., no battery mode). For example, the electronic device (101) may monitor the load current supplied to the system (340) from the second charger (320).
[0123] In operation 1030, the electronic device (101) according to one embodiment determines whether the supplied power is greater than or equal to a specified threshold value. If the supplied power is greater than or equal to the specified threshold value (e.g., the result of operation 1030 is "Yes"), the electronic device (101) may perform operation 1040. If the supplied power is less than the specified threshold value (e.g., the result of operation 1030 is "No"), the electronic device (101) may perform operation 1050. For example, the electronic device (101) may determine whether the load current supplied to the system (340) from the second charger (320) is a high power section in which the load current is greater than or equal to about 1000 mA, or a low power section in which the load current supplied to the system (340) from the second charger (320) is less than or equal to about 1000 mA. In one embodiment, the figure of about 1000 mA dividing the high power section and the low power section is only an example and the present disclosure is not limited thereto.
[0124] According to one embodiment, the electronic device (101) can adjust the specified threshold value based on the state of the electronic device (101). For example, the electronic device (101) can determine whether the electronic device (101) is in the specified state based on determining that the electronic device (101) is in a first state (e.g., no battery mode). The electronic device (101) can adjust the specified threshold value to a specified value corresponding to the determined state. For example, the electronic device (101) can adjust the threshold value dividing the high power section and the low power section based on the state of the electronic device (101).
[0125] According to one embodiment, the designated state of the electronic device (101) may include various states related to the operation of the electronic device (101).

The designated state of the electronic device (101) is not limited to the examples mentioned above.
[0126] According to one embodiment, the electronic device (101) can adjust the threshold value for each state of the electronic device (101). For example, the electronic device (101) can set the threshold value to a second value different from the default value when the electronic device (101) is in the second state. The electronic device (101) can set the threshold value to a third value different from the second value when the electronic device (101) is in the third state. The electronic device (101) can set the threshold value to a fourth value different from the second value when the electronic device (101) is in the fourth state. The electronic device (101) can set the threshold value to a fifth value different from the second value when the electronic device (101) is in the fifth state. The electronic device (101) can set the threshold value to a sixth value different from the second value when the electronic device (101) is in the sixth state.
[0127] In operation 1040, the electronic device (101) according to one embodiment may control the second charger (320) to output a first voltage that is greater than or equal to a specified reference voltage when the supplied power is greater than or equal to a specified threshold value (e.g., the result of operation 1030 is “Yes”).
[0128] According to one embodiment, the electronic device (101) can set the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) to a first voltage that is greater than or equal to the reference voltage in a high-power section where the load current is large (e.g., a section where the load current is about 1000 mA or more). According to one embodiment, the electronic device (101) can increase the efficiency of the second charger (320) by setting the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) to a first voltage that is a high voltage in a high-power section where the load current is large (e.g., a section where the load current is about 1000 mA or more).
[0129] In operation 1050, the electronic device (101) according to one embodiment may control the second charger (320) to output a second voltage that is less than a specified reference voltage when the supplied power is less than a specified threshold value (e.g., the result of operation 1030 is “No”).
[0130] According to one embodiment, the electronic device (101) can set the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) to a second voltage lower than the reference voltage in a low power section where the load current is small (e.g., a section where the load current is less than about 1000 mA). According to one embodiment, the electronic device (101) can increase the efficiency of the individual power supplies (341, 342) by setting the output voltage (e.g., VSYS of FIG. 3) of the second charger (320) to a second voltage lower than the reference voltage in a low power section where the load current is small (e.g., a section where the load current is less than about 1000 mA).
[0131] FIG. 11 is a flowchart illustrating an operation of limiting the performance of a sub-circuit based on the type of power supply while an electronic device (101) is in no battery mode according to one embodiment.
[0132] The operations illustrated in FIG. 11 may be performed by instructions stored in a memory (e.g., memory (130) of FIG. 1). For example, the instructions, when executed by a processor (e.g., processor (120) of FIG. 1), may cause an electronic device (e.g., electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 11.
[0133] At least some of the operations illustrated in FIG. 11 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 11.
[0134] According to one embodiment, at least some of the operations illustrated in FIG. 11 may be performed sequentially.
[0135] According to one embodiment, at least some of the operations illustrated in FIG. 11 may be performed in parallel (simultaneously).
[0136] Hereinafter, with reference to FIG. 11, an operation of limiting the performance of a sub-circuit based on the type of power supply while an electronic device (101) according to one embodiment is in no battery mode will be described.
[0137] In operation 1110, the electronic device (101) according to one embodiment may execute a no-battery mode (e.g., transition to a first state). For example, the electronic device (101) may execute a no-battery mode by performing at least some of the operations described with reference to FIG. 6 .
[0138] In operation 1120, the electronic device (101) according to one embodiment can check the type of an external device (e.g., the external device (301) of FIG. 3). For example, the electronic device (101) can check the maximum output power of the external device (301).
[0139] In operation 1130, the electronic device (101) according to one embodiment may adjust the performance of a plurality of components included in the electronic device (101) based on the type of the identified external device (301). For example, the electronic device (101) may selectively limit the performance of the plurality of components included in the electronic device (101) according to the maximum output power of the external device (301). When the maximum output power of the external device (301) is low, the electronic device (101) may prevent or reduce abnormal operation of the electronic device (101) by limiting the performance of at least some of the plurality of components.
[0140] The plurality of components included in the electronic device (101) may include at least some of the components of the electronic device (101) described with reference to FIG. 1. For example, the plurality of components included in the electronic device (101) may include a processor (120), a memory (130), an input module (150), an audio output module (155), a display module (160), an audio module (170), a sensor module (176), an interface (177), a connection terminal (178), a haptic module (179), a camera module (180), a power management module (188), a battery (189), a communication module (190), a subscriber identification module (196), or an antenna module (197).
[0141] In the present disclosure, adjusting the performance of a plurality of components may be interpreted to mean limiting a portion of the functions of the electronic device (101) provided by using the components of the electronic device (101) described with reference to FIG. 1. For example, when the electronic device (101) limits the performance of the display module (160), the driving frequency of the display module (160) may be set low, the luminance of the display module (160) may be set low, or the resolution of the display module (160) may be set low.
[0142] According to one embodiment, operation 1130 may include operation 1131, operation 1132, operation 1133, operation 1134, or operation 1135.
[0143] In operation 1131, the electronic device (101) according to one embodiment may determine whether the maximum output power of the external device (301) is greater than or equal to about 45 W. If the maximum output power of the external device (301) is greater than or equal to about 45 W (e.g., the result of operation 1131 is “Yes”), the electronic device (101) may perform operation 1132. If the maximum output power of the external device (301) is less than about 45 W (e.g., the result of operation 1131 is “No”), the electronic device (101) may perform operation 1133.
[0144] In operation 1132, the electronic device (101) according to one embodiment may not limit the performance of the plurality of components when the maximum output power of the external device (301) is greater than or equal to about 45 W. For example, the electronic device (101) may set the performance of the plurality of components to the maximum when the maximum output power of the external device (301) is greater than or equal to about 45 W while in the first state. For example, the electronic device (101) may set the brightness of the display module (160) to the maximum value.
[0145] In operation 1133, the electronic device (101) according to one embodiment may determine whether the maximum output power of the external device (301) is greater than or equal to about 25 W. If the maximum output power of the external device (301) is greater than or equal to about 25 W (e.g., the result of operation 1131 is “Yes”), the electronic device (101) may perform operation 1132. If the maximum output power of the external device (301) is less than about 25 W (e.g., the result of operation 1131 is “No”), the electronic device (101) may perform operation 1135.
[0146] In operation 1134, the electronic device (101) according to one embodiment may limit the performance of at least some components among the plurality of components to about 90% of the maximum performance if the maximum output power of the external device (301) is greater than or equal to about 25 W (e.g., the result of operation 1131 is “Yes”). For example, the electronic device (101) may limit the luminance of the display module (160) to about 90% of the maximum luminance value. In operation 1134, the value of about 90% for limiting the performance of the component is only one example, and the present disclosure is not limited thereto.
[0147] In operation 1135, the electronic device (101) according to one embodiment may limit the performance of at least some of the plurality of components to about 80% of the maximum performance if the maximum output power of the external device (301) is less than about 25 W (e.g., the result of operation 1131 is “No”). For example, the electronic device (101) may limit the luminance of the display module (160) to about 80% of the maximum luminance value. In operation 1135, the value of about 80% for limiting the performance of the component is only an example, and the present disclosure is not limited thereto. However, the degree to which the performance of the component is limited in operation 1135 may be greater than the degree to which the performance of the component is limited in operation 1134.
