When both switches (411, 431) are turned on, power can be supplied to the power supply circuit (210) based on, for example, narrow VDC (NVDC), but there is no limitation thereto. In one embodiment, the embedded circuit (220), the power delivery integrated circuit (PDIC) (441), or the power operating logic (443) (e.g., always-on power operating logic) can control the power supplied to various components included in the electronic device (101) based on the power supplied from the power supply circuit (210). The embedded circuit (220) can, for example, control the system power. The PDIC (441) can supply power to the system based on, for example, a TA (410) input of a USB-C type. The power usage logic (443) can supply power to hardware that is constantly in use, such as a keyboard. In one embodiment, a hang or a stuck state may occur in the system of the electronic device (101) for an unclear reason. The embedded circuit (220) may enter an inoperable state even when the operating voltage is supplied by the power supply circuit (210) due to the hang or stuck state of the system. A user of the electronic device (101) can reset the embedded circuit (220) based on an input through the input interface (240) without having to disassemble and reassemble the battery (430) from the electronic device (101). Referring to FIGS. 5a and 5b, the control circuit (230) can confirm input through the input interface (240) based on checking the status (531, 533) of the input interface pin (not shown) for communication with the input interface (240).For example, the control circuit (230) can confirm that there is no input (e.g., a press event) through the input interface (240) when a signal in a high state (531) is detected. The control circuit (230) can confirm that there is an input through the input interface (240) when a signal in a low state (533) is detected.

[0052] According to one embodiment, in operation 303, the electronic device (101) may determine whether the embedded circuit (220) is inoperable based on a signal provided from the embedded circuit (220) of the electronic device (101) in response to the input and a time period during which the input is maintained. According to one embodiment, the embedded circuit (220) may be determined to be inoperable if it is in a hung state and / or a stuck state. For example, the embedded circuit (220) may be determined to be inoperable if it does not send a response signal (e.g., a signal indicating an operating state).

[0053] In one embodiment, the control circuit (230) may start a configured timer based on determining that an input is received through the input interface (240) (e.g., that the input interface pin is in a low state). The control circuit (230) may start the timer, for example, when the state of the input interface pin changes from a high state to a low state. In one embodiment, the timer may be driven when the input through the input interface (240) is maintained. The control circuit (230) may end the configured timer based on determining that the state of the input through the input interface (240) has changed. The control circuit (230) may end the timer, for example, when the state of the input interface pin changes from a low state to a high state. In one embodiment, when the input interface is implemented as a power button, the timer may be ended when a press event of the power button is not detected. In one embodiment, the timer can be set based on a resistance value corresponding to a ground resistor (453) connected to a time setting pin (451) of the control circuit (230). Referring to FIG. 4, the ground resistor (453) can be disposed between the control circuit (230) and the ground (455). The ground resistor (453) can also be included within the control circuit (230). Referring to FIG. 5A, the control circuit (230) can determine a time interval corresponding to the timer based on a voltage level (541) identified through the time setting pin (451). The timer can be set to, for example, 4 seconds, but is not limited thereto. In one embodiment, when a pull-up resistor (not shown) is disposed between the control circuit (230) and the power supply circuit (210) through the time setting pin (451), a voltage level (545) corresponding to VDD (543) can be detected. If the timer is set based on the resistance value corresponding to the pull-up resistor, the timer can be set to 15 seconds, for example, and there is no limit to the specific value.

[0054] In one embodiment, when an input through the input interface (240) is confirmed by the embedded circuit (220), the embedded circuit (220) can output a signal indicating the operating state of the embedded circuit (220). The control circuit (230) can confirm the operating state of the embedded circuit (220) based on the signal provided from the embedded circuit (220) in response to the input. Referring to FIG. 5A, the control circuit (230) can confirm, for example, a signal toggle in which the signal state output from the embedded circuit (220) changes between a high level (521) and a low level (523) at a set cycle. In FIG. 5A, the signal toggle is illustrated as a Pulse at an interval of 1.172 s (seconds), but is not limited thereto. Referring to FIG. 5b, the control circuit (230) can also confirm that the signal state output from the embedded circuit (220) is maintained at a low level (525). The control circuit (230) can confirm whether the embedded circuit (220) is inoperable based on the time period during which the signal state output from the embedded circuit (220) is maintained and the time period during which the input through the input interface (240) is maintained.

[0055] In one embodiment, at operation 305, the electronic device (101) may provide a control signal to the power supply circuit (210) so that the power supply circuit (210) of the electronic device (101) resets the embedded circuit (220) based on determining that the embedded circuit (220) is inoperable.

[0056] In one embodiment, the control circuit (230) can check whether a time period during which a signal provided from the embedded circuit (220) and an input through the input interface (240) are maintained satisfies a condition for resetting the embedded circuit (220). The condition may include that the state of the signal provided from the embedded circuit (220) is maintained during a time period corresponding to a set timer, and that the input is maintained during a time period corresponding to the set timer. Referring to FIG. 5A, the control circuit (230) can check a signal toggle in which a signal output from the embedded circuit (220) changes between a high level (521) and a low level (523) while power at a voltage level (511) corresponding to VDD (513) is provided to the embedded circuit (220) by the power supply circuit (210). In one embodiment, the control circuit (230) can restart the set timer based on determining that the state of a signal provided from the embedded circuit (220) changes before the time interval (547) corresponding to the set timer elapses. The control circuit (230) can determine that the condition for resetting the embedded circuit (220) is not satisfied even at the point in time (535) when the time interval during which the input is maintained exceeds the time interval (547) corresponding to the set timer, because the signal toggle occurs before the time interval (547) corresponding to the set timer elapses.

[0057] In one embodiment, referring to FIG. 5B, the control circuit (230) can determine that a signal output from the embedded circuit (220) is maintained at a low level (525) while power of a predetermined voltage level (511) is provided to the embedded circuit (220) by the power supply circuit (210). In one embodiment, based on the state of the signal output from the embedded circuit (220) being maintained until the time period during which the input through the input interface (240) is maintained exceeds (535) a time period (547) corresponding to a set timer, the control circuit (230) can determine that a condition for resetting the embedded circuit (220) is satisfied. Based on determining that the condition is satisfied, the control circuit (230) can provide a control signal to the power supply circuit (210) during a time period set to cause the power supply circuit (210) to reset the embedded circuit (220). The power supply circuit (210) can turn off the embedded circuit (220) based on lowering the constant voltage provided to the embedded circuit (220) to a low level (515) during a time period (517) during which a control signal is provided. The power supply circuit (210) can turn on the embedded circuit (220) based on raising the voltage provided to the embedded circuit (220) to a level (519) corresponding to VDD after a control signal is provided from the control circuit (230). In one embodiment, the operation of the control circuit (230) providing the control signal to the power supply circuit (210) can include an operation of changing the state of an output pin (not shown) of the control circuit (230) to a low state. When the embedded circuit (220) is reset by the power supply circuit (210), both the PDIC (441) and the power usage logic (443) are reset, so the system of the electronic device (101) can also be reset.

[0058] According to the above-described method, when the embedded circuit (220) is reset, if the system hangs or gets stuck for an unknown reason, the system can be rebooted by inputting only through the input interface (240) without disassembling and reassembling the battery (430). This can improve the usability of the electronic device (101).

For example, the electronic device (101) may be implemented in the same or similar manner as the electronic device (101) of FIG. 4. The electronic device (101) according to the embodiment of FIG. 6A may reset the embedded circuit (220) without an input through the key interface (610). The key interface (610) may include an input interface, such as a power button or a keyboard, for example. The control circuit (230) may reset the embedded circuit (220) based on providing a control signal to the power supply circuit (210). The control circuit (230) may reset the embedded circuit (220) based on providing a control signal to the embedded circuit (220) through a signal line (623) connected to a reset pin (not shown) of the embedded circuit (220). In one embodiment, the signal line (623) for resetting the embedded circuit (220), the PDIC (441), and / or the power usage logic (443) may be optionally implemented. A method for the control circuit (230) to reset the embedded circuit (220) without an input through the key interface (610) will be described later in FIG. 7. In one embodiment, a pull-up resistor (621) may be arranged between the time setting pin (451) of the control circuit (230) and the power supply circuit (210). When a pull-up resistor (621) is used instead of the ground resistor illustrated in Fig. 4, the time interval corresponding to the timer can be set to, for example, 15 seconds, but is not limited thereto.

[0061] Referring to FIG. 6B, according to one embodiment, the control circuit (230) may be connected to variable resistors (631, 633, 651, 653). The variable resistors (631, 633) (e.g., the first variable resistor (631), the second variable resistor (633)) may be connected to the time setting pin (451) of the control circuit (230). The time interval of the timer may be set based on the resistance value corresponding to the variable resistors (631, 633). For example, the time interval corresponding to the timer may be set to a value of 15 seconds or less. The control circuit (230) may further include an enable setting pin (641) for setting the time interval for providing a control signal to the power supply circuit (210). A variable resistor (651, 653) (e.g., a third variable resistor (651), a fourth variable resistor (653)) may be connected to the enable setting pin (641) of the control circuit (230). A time interval for providing a control signal to the power supply circuit (210) may be set based on the resistance value corresponding to the variable resistor (651, 653).

The electronic device (101) can determine whether a hang or a stuck state of the system occurs based on whether the state of the signal output from the embedded circuit (220) is maintained for a set time period based on, for example, a resistance value corresponding to a resistor connected to a time setting pin (451).

[0065] In one embodiment, the time interval may be set based on a resistance value corresponding to a pull-up resistor (e.g., pull-up resistor (621) of FIG. 6A) connected to the control circuit (230). In one embodiment, the time interval may also be set based on a resistance value corresponding to a variable resistor (e.g., variable resistors (631, 633) of FIG. 6B) connected to the control circuit (230).

A control circuit (e.g., a control circuit (230)) can check the status of a signal output from the embedded circuit and an input status through an input interface. The control circuit can provide a control signal to the power supply circuit during a set time period (840) based on whether a time period (820) during which the status of the signal output from the embedded circuit is maintained and a time period (830) during which the input status through the input interface is maintained exceed a time period corresponding to a set timer. The power supply circuit can turn off the embedded circuit during the set time period (840).

For example, a control circuit (e.g., control circuit (230)) may verify the input based on a change in the state of an input interface pin for communication with the input interface.

[0072] According to one embodiment, in operation 903, the electronic device (101) may determine whether the state of a signal output by an embedded circuit (e.g., embedded circuit (220)) is maintained based on an input through an input interface. The electronic device (101) may determine, for example, whether the state of the signal output from the embedded circuit is maintained at a high level or a low level for a time period corresponding to a set timer. Based on determining that the state of the signal is not maintained (operation 903-No), the electronic device (101) may initialize the timer in operation 905. The electronic device (101) may restart the timer based on, for example, a change in the signal output from the embedded circuit.

[0073] According to one embodiment, based on the state of the signal being maintained (operation 903 - Yes), in operation 907, the electronic device (101) may determine whether the input through the input interface is maintained. For example, the electronic device (101) may determine whether the state of the input interface pin is maintained in a low state. Based on determining that the input through the input interface is not maintained (operation 907 - No), the electronic device (101) may terminate the timer in operation 909. The electronic device (101) may terminate the timer, for example, based on determining that the performance of an input operation (e.g., a button press operation) through the input interface has been stopped.

[0074] According to one embodiment, based on determining that input through the input interface is maintained (operation 907-Yes), the electronic device (101) may, in operation 911, provide a control signal to the power supply circuit. For example, the electronic device (101) may change a pin of a control circuit connected to the power supply circuit to a low state so that the power supply circuit turns off the embedded circuit for a set time period.
