DETAILED DESCRIPTION

[0059] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present disclosure. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0060] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0061] In the following description, the terms "first / second / third" are used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first / second / third" can be interchanged with the specific order or sequence where permitted so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein are only for the purpose of describing the embodiments of the present disclosure and are not intended to limit the present disclosure.

[0063] In order to better understand the embodiments of the present disclosure, some application scenarios in related technologies are described below:

[0064] In some embodiments, Figure 1 As shown, the electronic equipment includes:

[0065] System power supply module 101;

[0066] A battery power supply module 102 connected to the system power supply module 101;

[0067] At least one first component 103 connected to the system power supply module 101;

[0068] The clock module 104 is connected to the system power supply module 101;

[0069] The second switch element 107 of the power management module 105 is located between the battery power supply module 102 and the system power supply module 101;

[0070] When the electronic device is turned off, the second switch element 107 is disconnected; or, when the electronic device is turned off, the second switch element 107 is closed, and the battery power supply module 102 supplies power to the clock module 104 through the system power supply module 101 .

[0071] It should be noted that the clock module 104 is configured to supply power to the system clock. If the clock module 104 is disconnected from the power supply, the system time will be reset after the electronic device is restarted and cannot be maintained.

[0072] Here, on the one hand, when the electronic device is turned off, if the second switch element 107 is disconnected, the electrical connection between the battery power module 102 and the system power module 101 is disconnected, and the battery power module 102 cannot power the clock module 104 through the system power module 101, resulting in the electronic device being unable to maintain the accuracy of the system clock. Alternatively, when the electronic device is turned off, if the second switch element 107 is closed, the accuracy of the system clock can be maintained. However, since the battery power module 102 continues to power the system power module 101, and the system power module 101 continues to power at least one first component 103, the shutdown leakage current of the electronic device is large. After the electronic device is turned off, the power of the electronic device will still decrease rapidly, resulting in the need to recharge the electronic device before it can be turned on, and the user experience is poor. It can be seen from this that when the electronic device is turned off, the electronic device cannot ensure the accuracy of the system clock while reducing the shutdown leakage current of the electronic device.

[0073] On the other hand, in order to ensure the accuracy of the system clock, the second switch element 107 is closed when the electronic device is turned off. At this time, the electrical connection between the first component 103 directly connected to the system power supply module 101 and the system power supply module 101 cannot be disconnected, resulting in the first component 103 being unable to be reset when the first component 103 is abnormal, resulting in the first component 103 being unable to return to normal, resulting in a poor user experience.

[0074] In some embodiments, the second switch element 107 may be a metal-oxide-semiconductor field-effect transistor (MOSFET) in a power management chip (PMIC, Power ManageIC), and the MOS tube is also turned on when the power is turned off. The main function of the MOS tube is to detect voltage and current to provide safety protection for the battery power supply module 102 and the system power supply module 101.

[0075] In some embodiments, when the electronic device is in the factory state, the electronic device may be in the shipping mode. At this time, the second switch element 107 in the electronic device may be disconnected. In this way, the leakage current of the entire system of the electronic device may be reduced, so that the electronic device can be stored in the warehouse for a longer time.

[0076] In some embodiments, Figure 2As shown, the electronic device further includes a second component 110 , and the battery power supply module 102 is connected to the second component 110 .

[0077] Here, when the electronic device is turned off, the electrical connection between the second component 110 directly connected to the battery power module 102 and the battery power module 102 cannot be disconnected, resulting in the inability to hard reset the second component 110 when the second component 110 is abnormal, resulting in the inability to restore the second component 110 to normal, resulting in a poor user experience.

[0078] It is understandable that in some application scenarios, the electronic device can only be restored to normal by unplugging the battery and then replugging it. However, some products, such as mobile phone batteries, cannot be disassembled, and users cannot replug the batteries. At this time, in the case of abnormality of the first component 103 and / or the second component 110, it is difficult to reset the second component 110 and / or the first component 103, resulting in difficulty in restoring the first component 103 and / or the second component 110 to normal.

[0079] Based on this, Figure 3 and Figure 4 As shown, an embodiment of the present disclosure provides an electronic device, the electronic device comprising:

[0080] System power supply module 101;

[0081] A battery power supply module 102, electrically connected to the system power supply module 101;

[0082] At least one first component 103, electrically connected to the system power supply module 101;

[0083] A clock module 104, electrically connected to the system power supply module 101; or connected to the battery power supply module 102; the clock module 104 is configured to determine the system clock of the electronic device;

[0084] Among them, when the electronic device is turned off, the electrical connection between the system power supply module 101 and at least one of the first components 103 is disconnected, and the battery power supply module 102 directly powers the clock module 104, or the battery power supply module 102 powers the clock module 104 via the system power supply module 101.

[0085] In some embodiments, the electronic devices may include but are not limited to mobile communication terminals, portable entertainment devices, wearable devices, household appliances and special equipment. Among them, mobile communication terminals may include but are not limited to mobile phones, tablet computers and smart watches; portable entertainment devices may include but are not limited to audio players and digital cameras; wearable devices may include but are not limited to smart bracelets and smart glasses; household appliances may include but are not limited to televisions, stereos and video recorders; special equipment may include but are not limited to drones and electronic game consoles.

[0086] In some embodiments, the battery power module 102 may include a battery, and the battery power module 102 may be configured to power other components connected to the battery power module 102 through the battery. For example, the battery power module 102 may be a module that supplies system power through a VBAT pin.

[0087] In some embodiments, the system power supply module 101 may be electrically connected to the battery power supply module 102, and configured to power at least one component and / or the clock module 104 connected to the system power supply module 101 through the power provided by the battery power supply module 102 to the system power supply module 101. Exemplarily, the system power supply module 101 may be a module that is battery-powered through a VSYS pin.

[0088] In some embodiments, when the system power supply module 101 and the battery power supply module 102 are electrically connected, the battery power supply module 102 can supply power to the system power supply module 101, and the system power supply module 101 can supply power to the first component 103 and / or the clock module 104 through the power provided by the battery power supply module 102 to the system power supply module 101. When the electrical connection between the system power supply module 101 and the battery power supply module 102 is disconnected, the system power supply module 101 cannot independently supply power to the first component 103 and / or the clock module 104.

[0089] In some embodiments, when the electronic device is turned off, the electrical connection between the battery power module 102 and the system power module 101 is not disconnected.

[0090] In some embodiments, the clock module 104 may be a real-time clock (RTC) chip.

[0091] In some embodiments, when the electronic device is turned on, the system power supply module 101 is electrically connected to the battery power supply module 102, and the system power supply module 101 is electrically connected to at least one component. The clock module 104 is directly electrically connected to the battery power supply module 102, or is indirectly electrically connected to the battery power supply module 102. For example, the clock module 104 can be directly electrically connected to the system power supply module 101 to be indirectly electrically connected to the battery power supply module 102. When the electronic device is turned off, only the connection between the system power supply module 101 and the first component 103 can be disconnected. At this time, the direct electrical connection or indirect electrical connection between the clock module 104 and the battery power supply module 102 can be maintained. That is, when the electronic device is turned off, the battery power supply module 102 can still directly power the clock module 104, or the battery power supply module 102 can indirectly power the clock module 104 through the system power supply module 101.

[0092] It can be understood that in the embodiment of the present disclosure, when the electronic device is turned off, it is only necessary to ensure that the system power supply module 101 stops supplying power to at least one first component 103, and the battery power supply module 102 is able to directly and / or indirectly supply power to the clock module 104, without limiting the method by which the electrical connection between the system power supply module 101 and at least one component is disconnected.

[0093] Exemplarily, when the electronic device is turned on, the clock module 104 can be connected to the battery power module 102; the system power module 101 and the battery power module 102 are electrically connected, and the system power module 101 and at least one component are electrically connected. When the electronic device is turned off, the connection between the system power module 101 and the battery power module 102 can be disconnected, and / or the connection between the system power module 101 and at least one component can be disconnected. At this time, the system power module 101 stops supplying power to at least one first component 103, and the battery power module 102 can directly supply power to the clock module 104.

[0094] Exemplarily, when the electronic device is turned on, the clock module 104 can be connected to the system power supply module 101; the system power supply module 101 and the battery power supply module 102 are electrically connected, and the system power supply module 101 and at least one component are electrically connected. When the electronic device is turned off, the electrical connection between the system power supply module 101 and the battery power supply module 102 is not disconnected, and the connection between the system power supply module 101 and at least one component is disconnected. At this time, the system power supply module 101 stops supplying power to at least one first component 103, and the battery power supply module 102 can directly supply power to the clock module 104.

[0095] In some embodiments, the first component 103 may be any type of electronic component. For example, the first component 103 may include but is not limited to at least one of the following: a resistor, a capacitor, a potentiometer, an electron tube, an inductor, a heat sink, a connector, an electroacoustic device, a laser device, an electronic display device, an optoelectronic device, a sensor, a power supply, a switch, a relay, a printed circuit board, and an integrated circuit.

[0096] In some embodiments, when the electronic device is restarted, the electrical connection between the system power supply module 101 and at least one of the first components 103 is restored. In this way, when at least one of the first components 103 is abnormal, the first component 103 can be reset by re-powering on the first component 103, thereby reducing the situation where the first component 103 cannot be restored to normal due to failure to reset, thereby ensuring the reliability of the operation of the first component 103.

[0097] In an embodiment of the present disclosure, an electronic device is provided, and the electronic device includes: the electronic device includes: a system power supply module 101; a battery power supply module 102, electrically connected to the system power supply module 101; at least one first component 103, electrically connected to the system power supply module 101; a clock module 104, electrically connected to the system power supply module 101; or connected to the battery power supply module 102; the clock module 104 is configured to determine the system clock of the electronic device; wherein, when the electronic device is turned off, the electrical connection between the system power supply module 101 and at least one of the first components 103 is disconnected, and the battery power supply module 102 directly supplies power to the clock module 104, or the battery power supply module 102 supplies power to the clock module 104 via the system power supply module 101.

[0098] Here, on the one hand, since the electrical connection between the system power supply module 101 and at least one of the first components 103 is disconnected when the electronic device is turned off, the power supply to at least one of the first components 103 can be disconnected when the electronic device is turned off. In this way, the shutdown leakage current of the electronic device can be reduced to reduce the situation where the user needs to frequently charge the electronic device when the electronic device is turned off before the electronic device can be restarted, ensuring a good user experience. For example, the shutdown leakage current in the related art will be between 0.4-1mA, and the disclosed embodiment can reduce the shutdown leakage current to below 0.1mA, greatly reducing the loss of battery power after the system is shut down. On the other hand, when the electronic device is turned off, the battery power supply module 102 can directly power the clock module 104, or the battery power supply module 102 can power the clock module 104 via the system power supply module 101, so when the electronic device is turned off, it can be powered by continuously powering the clock module 104 to keep the timing of the system clock. In this way, the accuracy of the system clock of the electronic device can be ensured, ensuring that the user can use the correct system clock after restarting the electronic device.

[0099] It can be seen that the embodiment of the present disclosure can simultaneously disconnect the power supply to at least one first component 103 when the electronic device is turned off, and maintain the power supply to the clock module 104. In this way, the accuracy of the system clock of the electronic device can be ensured while reducing the shutdown leakage current of the electronic device, ensuring a good user experience.

[0100] In some embodiments, the clock module 104 is connected to the battery power module 102;

[0101] When the electronic device is turned off, the electrical connection between the battery power supply module 102 and the system power supply module 101 is disconnected.

[0102] It can be understood that, when the system power supply module 101 and the battery power supply module 102 are electrically connected, the battery power supply module 102 can supply power to the system power supply module 101, and the system power supply module 101 can supply power to the first component 103 and / or the clock module 104 through the power provided by the battery power supply module 102 to the system power supply module 101. When the electrical connection between the system power supply module 101 and the battery power supply module 102 is disconnected, the system power supply module 101 cannot independently supply power to the first component 103 and / or the clock module 104. In other words, when the electrical connection between the system power supply module 101 and the battery power supply module 102 is disconnected, the electrical connection between the system power supply module 101 and at least one first component 103 is disconnected.

[0103] In some embodiments, Figure 5 As shown, the electronic device includes: a system power supply module 101; a battery power supply module 102, electrically connected to the system power supply module 101; at least one first component 103, electrically connected to the system power supply module 101; a clock module 104, connected to the battery power supply module 102; a second switch element 107, located between the battery power supply module 102 and the system power supply module 101; when the electronic device is turned off, the second switch element 107 is disconnected. It can be understood that when the second switch element 107 is disconnected, the electrical connection between the battery power supply module 102 and the system power supply module 101 is disconnected, and at this time, the electrical connection between the system power supply module 101 and at least one first component 103 is disconnected. In this way, the waste of power resources caused by continuously supplying power to the first component 103 when the electronic device is turned off can be reduced, and the power consumption of the electronic device can be reduced. In addition, the electronic device can continuously supply power to the clock module 104 through the battery power supply module 102. In this way, the accuracy of the system clock can be ensured.

[0104] In some embodiments, Figure 6 As shown, the electronic device includes a power management module 105, which is used to control the electrical connection between the system power supply module 101 and at least one component to be disconnected when the electronic device is turned off, and to control the electrical connection between the system power supply module 101 and at least one component to be restored when the electronic device is turned on.

[0105] In some embodiments, the second switch element 107 is connected to the power management module 105 , and the power management module 105 can be configured to control the second switch element 107 to be disconnected when the electronic device is turned off; and to control the second switch to be closed when the electronic device is turned on.

[0106] In some embodiments, the second switch element 107 may be an electronic relay, a reed relay, a triode switch, a field effect transistor, a diode switch, a thyristor, or a photocoupler.

[0107] In some embodiments, the power management module 105 may be a PMIC.

[0108] In some embodiments, the second switch element 107 may be a MOS transistor (eg, Figure 6 shown).

[0109] In the embodiment of the present disclosure, since the clock module 104 is connected to the battery power module 102 and the electronic device is turned off, the electrical connection between the battery power module 102 and the system power module 101 is disconnected. Therefore, when the electronic device is turned off, the electrical connection between the battery power module 102 and the system power module 101 is disconnected. At this time, the electrical connection between the system power module 101 and at least one first component 103 is disconnected. In this way, the waste of electric power resources caused by continuously supplying power to the first component 103 when the electronic device is turned off can be reduced, the power consumption of the electronic device can be reduced, and the shutdown leakage current of the electronic device can be reduced. In addition, the electronic device can continuously supply power to the clock module 104 through the battery power module 102. In this way, the accuracy of the system clock can be ensured.

[0110] In some embodiments, Figure 7 and Figure 8 As shown, the electronic device further includes:

[0111] The first switch element 106 is located between at least one of the first components 103 and the system power supply module 101 , and is connected to at least one of the first components 103 and the system power supply module 101 , respectively.

[0112] In some embodiments, when the electronic device is turned off, the first switch element 106 is disconnected. It is understood that when the first switch element 106 is disconnected, the electrical connection between the system power supply module 101 and the first component 103 is disconnected. When the electronic device is turned on, the first switch element 106 is closed. It is understood that, compared with the method of taking a long time to control the second switch element 107 in the power management module 105 to be disconnected, the time for controlling the separately set first switch element 106 to be closed is shorter. In this way, the efficiency of controlling the first switch element 106 to be closed to disconnect the electrical connection between the system power supply module 101 and at least one component can be improved.

[0113] In some embodiments, the first switch element 106 may be an electronic relay, a reed relay, a triode switch, a field effect transistor, a diode switch, a thyristor, or a photocoupler.

[0114] In some embodiments, the first switch element 106 may be a single-pole single-throw switch.

[0115] In the embodiment of the present disclosure, since the first switch element 106 is located between at least one first component 103 and the system power supply module 101, and is respectively connected to at least one first component 103 and the system power supply module 101, the switching state of the first switch element 106 can be flexibly controlled to control the connection state between the first component 103 and the system power supply module 101. In this way, when the electronic device is turned off, the connection state between the first component 103 and the system power supply module 101 can be disconnected by controlling the switching state of the first switch element 106, thereby reducing the shutdown leakage current of the electronic device.

[0116] In some embodiments, Figure 7 As shown, the clock module 104 is electrically connected to the system power supply module 101;

[0117] When the electronic device is turned off, the first switch element 106 is disconnected, and the battery power supply module 102 supplies power to the clock module 104 via the system power supply module 101 .

[0118] In some embodiments, Fig. 9 As shown, the electronic device includes: a system power supply module 101; a battery power supply module 102, electrically connected to the system power supply module 101; at least one first component 103, electrically connected to the system power supply module 101; a clock module 104, electrically connected to the system power supply module 101; a first switch element 106, located between at least one of the first components 103 and the system power supply module 101, and connected to at least one of the first components 103 and the system power supply module 101 respectively; a second switch element 107, located between the battery power supply module 102 and the system power supply module 101, and connected to the battery power supply module 102 and the system power supply module 101 respectively; wherein, when the electronic device is turned off, the first switch element 106 is disconnected, and the second switch element 107 is closed, and the battery power supply module 102 supplies power to the clock module 104 via the system power supply module 101. When the electronic device is turned on, the first switch element 106 and the second switch element 107 are closed.

[0119] In the embodiment of the present disclosure, since the clock module 104 is electrically connected to the system power supply module 101, and when the electronic device is turned off, the first switch element 106 is disconnected, and the battery power supply module 102 supplies power to the clock module 104 via the system power supply module 101, the system power supply module 101 can be used to continuously supply power to the clock module 104 while the system power supply module 101 is disconnected from supplying power to at least one first component 103. In this way, when the electronic device is turned off, the shutdown leakage current can be reduced and the accuracy of the system clock can be ensured.

[0120] In some embodiments, Figure 8 As shown, the clock module 104 is connected to the battery power supply module 102;

[0121] Wherein, when the electronic device is turned off, the electrical connection between the battery power supply module and the system power supply module 101 is disconnected, and the battery power supply module 102 directly supplies power to the clock module 104; and / or

[0122] The first switch element 106 is turned off, and the battery power supply module 102 directly supplies power to the clock module 104 .

[0124] In the embodiment of the present disclosure, since the clock module 104 is connected to the battery power module 102, and when the electronic device is turned off, the first switch element 106 is disconnected, the first switch element 106 and / or the second switch element 107 are disconnected, and the battery power module 102 directly supplies power to the clock module 104, it is possible to disconnect the power supply of the system power module 101 to the at least one first component 103, and at the same time, the battery power module 102 can be used to directly supply power to the clock module 104. In this way, when the electronic device is turned off, the shutdown leakage current can be reduced and the accuracy of the system clock can be ensured.

[0125] In some embodiments, the electronic device further comprises:

[0126] Power management module 105;

[0127] The first switch element 106 is connected to the power management module 105;

[0128] Wherein, when the clock module 104 is connected to the battery power module 102 and the electronic device is turned off, the power management module 105 controls the first switch element 106 to be disconnected, and / or controls the connection between the battery power module 102 and the system power module 101 to be disconnected;

[0129] When the clock module 104 is connected to the system power supply module 101 and the electronic device is turned off, the power management module 105 controls the first switch element 106 to be turned off.

[0130] In some embodiments, the electronic device includes: a system power supply module 101; a battery power supply module 102, electrically connected to the system power supply module 101; at least one first component 103, electrically connected to the system power supply module 101; a clock module 104, connected to the battery power supply module 102, or connected to the system power supply module 101; a first switch element 106, connected to the power management module 105, located between at least one of the first components 103 and the system power supply module 101, and respectively connected to at least one of the first components 103 and the system power supply module 101; a second switch element 107, connected to the power management module 105, located between the battery power supply module 102 and the system power supply module 101, and respectively connected to the battery power supply module 102 and the system power supply module 101; wherein, when the electronic device is turned off, the first switch element 106 and / or the second switch element 107 are disconnected, and the battery power supply module 102 directly supplies power to the clock module 104. When the clock module 104 is connected to the system power supply module 101 and the electronic device is turned off, the power management module 105 controls the first switch element 106 to be disconnected and controls the second switch element 107 to be closed.

[0131] In the embodiment of the present disclosure, on the one hand, when the clock module 104 is connected to the battery power module 102 and the electronic device is turned off, the power management module 105 controls the first switch element 106 to be disconnected, and / or controls the connection between the battery power module 102 and the system power module 101 to be disconnected. At this time, the electrical connection between the battery power module 102 and the system power module 101 can be disconnected while the clock module 104 is continuously powered directly by the battery power module 102, and / or the physical connection between the system power module 101 and at least one first component 103 can be disconnected, that is, the power supply of the system power module 101 to at least one first component 103 can be disconnected. On the other hand, when the clock module 104 is connected to the system power module 101 and the electronic device is turned off, the power management module 105 controls the first switch element 106 to be disconnected. At this time, when the system power supply module 101 supplies power to the clock module 104, the system power supply module 101 can be disconnected from supplying power to the at least one first component 103. In this way, when the electronic device is shut down, the shutdown leakage current can be reduced and the accuracy of the system clock can be ensured.

[0132] In some embodiments, Fig. 9As shown, the power management module 105 is configured to control the connection between the system power supply module 101 and the battery power supply module 102 to be disconnected when the clock module 104 and the system power supply module 101 are connected and the power reserve of the battery power supply module 102 is less than the reserve threshold.

[0133] In some embodiments, the power management module 105 is configured to control the second switch element 107 described in any one of the embodiments of the present disclosure to be disconnected when the clock module 104 and the system power supply module 101 are connected and the power remaining of the battery power supply module 102 is less than the remaining threshold; and to control the second switch element 107 to be closed when the clock module 104 and the system power supply module 101 are connected and the power remaining of the battery power supply module 102 is greater than the remaining threshold.

[0134] In the embodiment of the present disclosure, since the power management module 105 is configured to disconnect the connection between the control system power module 101 and the battery power module 102 when the clock module 104 and the system power module 101 are connected and the power reserve of the battery power module 102 is less than the reserve threshold, when the power of the battery power module 102 is low, the battery power module 102 no longer continues to supply power to the system power module 101, and the system power module 101 no longer continues to supply power to the clock module 104. In this way, the leakage current of the electronic device can be reduced when the power reserve of the electronic device is low.

[0135] In some embodiments, Fig.11 As shown, the electronic equipment includes:

[0136] a third switch element 108, located between the second switch element 107 and the battery power module 102, and connected to the second switch element 107 and the battery power module 102 respectively;

[0137] A power-on module 109 is electrically connected to the battery power supply module 102 and the third switch element 108 respectively;

[0138] When the electronic device is turned off, the third switch element 108 is disconnected, and the battery power supply module 102 supplies power to the power-on module 109 ; when the electronic device is turned on, the power-on module 109 controls the third switch element 108 to be closed.

[0139] In some embodiments, the electronic device includes: a system power supply module 101; a battery power supply module 102, electrically connected to the system power supply module 101; and at least one first component 103, electrically connected to the system power supply module 101. A clock module 104, connected to the battery power supply module 102; the clock module 104 is configured to determine the system clock of the electronic device. A second switch element 107, located between the battery power supply module 102 and the system power supply module 101, is electrically connected to the battery power supply module 102 and the system power supply module 101, respectively. A third switch element 108, located between the second switch element 107 and the battery power supply module 102, is electrically connected to the second switch element 107 and the battery power supply module 102, respectively. A power-on module 109, is electrically connected to the battery power supply module 102 and the third switch element 108, respectively. When the electronic device is turned off, the third switch element 108 is disconnected, and the battery power supply module 102 supplies power to the power-on module 109 and the clock module 104; when the electronic device is turned on, the power-on module 109 controls the third switch element 108 to be closed.

[0140] In some embodiments, when the third switch element 108 is disconnected, the second switch element 107 is disconnected. When the third switch element 108 is closed, the second switch element 107 is closed. The second switch element 107 may be a MOS tube in the PMIC. It is understandable that when the third switch element 108 is disconnected, the battery power module 102 cannot supply power to the MOS tube connected to the third switch element 108, resulting in the disconnection of the electrical connection between the PMIC and the battery power module 102, and the PMIC cannot control the third switch element 108 to close so that the second switch element 107 is closed. That is, after the electronic device is turned off, the PMIC cannot control the MOS tube to turn on, resulting in the inability to restore the electrical connection between the battery power module 102 and the at least one first component 103 through the PMIC when the electronic device is turned on.

[0141] In some embodiments, the power-on module 109 is configured to control the third switch element 108 to close when a power-on instruction is detected. The power-on instruction may be an instruction generated by the electronic device when a touch operation acting on a predetermined key is detected. For example, the power-on instruction may be a power-on key of the electronic device.

[0142] In the embodiment of the present disclosure, on the one hand, a third switch element 108 is provided in the electronic device, which is connected to the second switch element 107 and the battery power module 102 respectively, and when the electronic device is turned off, the third switch element 108 is disconnected, and the battery power module 102 supplies power to the power module 109 and the clock module 104. At this time, when the electronic device is turned off, the connection between the battery power module 102 and the second switch element 107 can be disconnected, that is, the connection between the battery power module 102 and at least one component is disconnected, and the accuracy of the system clock can be ensured. In this way, the accuracy of the system clock can be ensured while reducing the shutdown leakage current of the electronic device. On the other hand, when the connection between the battery power module 102 and the second switch element 107 is disconnected, the battery power module 102 can directly supply power to the power module 109, so that the third switch element 108 controlled to be closed when the electronic device is turned on allows the current to be transferred to at least one component through the third element, and the battery power module 102 can supply power to at least one component. Reduce the situation where the battery power module 102 cannot be controlled to resume powering at least one component due to the disconnection of the electrical connection between the module for controlling the startup of the electronic device and the battery power module 102. In this way, the reliability of controlling the battery power module 102 to resume powering at least one component can be ensured when the electronic device is turned on.

[0143] In some embodiments, Fig.12 and Fig.13 As shown, including:

[0144] at least one second component 110;

[0145] When the conduction current of the second switch element 107 is greater than the flux threshold, at least one of the second components 110 is electrically connected to the system power supply module 101;

[0146] or,

[0147] When the conduction current of the second switch element 107 is less than the flux threshold, at least one of the second components 110 is electrically connected to the battery power supply module 102 .

[0148] In some embodiments, at least one second component 110 may include but is not limited to at least one of the following: resistors, capacitors, potentiometers, electron tubes, inductors, heat sinks, connectors, electroacoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, relays, printed circuit boards, and integrated circuits.

[0149] In some embodiments, the operating current of the second component 110 may be greater than the current threshold.

[0150] In some embodiments, when at least one of the second components 110 is electrically connected to the system power supply module 101 , any of the first components 103 described in the embodiments of the present disclosure may also include the second component 110 .

[0151] In the embodiment of the present disclosure, on the one hand, because when the conduction current of the second switch element 107 is greater than the flux threshold, at least one of the second components 110 is electrically connected to the system power supply module 101 (such as Fig.12 As shown), therefore, when the on-current of the second switch element 107 is large, the second component 110 in the electronic device can be connected to the system power supply module 101, so that when the electronic device is turned off, the connection between the system power supply module 101 and the second component 110 can be disconnected, so that as many components as possible in the electronic device stop working. In this way, the shutdown leakage current of the electronic device can be greatly reduced. On the other hand, since at least one of the second components 110 is electrically connected to the battery power supply module 102 (as shown) when the on-current of the second switch element 107 is less than the flux threshold, Fig.13 As shown in FIG. 1 , it is possible to ensure that when the second component 110 is required to work, the second component 110 can work with the large current provided by the battery power supply module 102. In this way, the reliability of the second component 110 when working can be ensured.

[0152] In some embodiments, Fig.14 As shown, the electronic device also includes:

[0153] a fourth switch element 111, located between the battery power supply module 102 and at least one of the second components 110, and connected to the battery power supply module 102 and at least one of the second components 110 respectively;

[0154] Wherein, when the electronic device is turned off, the fourth switch element 111 is disconnected.

[0155] In the embodiment of the present disclosure, since the fourth switch element 111 is located between the battery power module 102 and at least one of the second components 110, and is respectively connected to the battery power module 102 and at least one of the second components 110, when the electronic device is turned off, the fourth switch element 111 is disconnected. Therefore, when the electronic device is turned off, the connection between the battery power module 102 and at least one of the second components 110 can be disconnected, thereby reducing the shutdown leakage current of the electronic device.
