Abstract:
The present application provides a system-on-chip, comprising: a power supply pin, a power grounding pin, an over-charge voltage protection unit, an over-discharge voltage protection unit, a discharge overcurrent protection unit, a reference voltage generation unit, a frequency generation unit, a control unit, a wake-up unit, and a first switch unit. The system-on-chip further comprises a shipping pin. When the shipping pin receives a first signal, the system-on-chip enters a shipping mode; in the shipping mode, the first switch unit is turned off so that a battery stops supplying power to a system circuit, and at least part of the units of the system-on-chip are stopped from power supply; moreover, in the shipping mode, the wake-up unit is supplied with power, and the wake-up unit is used for causing the system-on-chip to exit the shipping mode. The present application further provides a battery assembly and an electronic device. The present application has the following advantages: current consumption of the battery in the transportation and storage process can be reduced, the electric quantity retention time of the battery is prolonged, and user experience is improved.
