  • Publication number: 20230275441
    Abstract: A battery protection circuit, which includes: a power supply terminal, a power ground terminal, an overcharge voltage protection sub-circuit, an over-discharge voltage protection sub-circuit, a discharge over-current protection sub-circuit, a reference voltage generation sub-circuit, a frequency generation sub-circuit, a controller and a first switch sub-circuit. The battery protection circuit further includes a shipping input terminal, the battery protection circuit is configured to enter a shipping mode when a first signal is received at the shipping input terminal, and in the shipping mode, at least one sub-circuit of the battery protection circuit is powered off. The present application also provides a battery pack and an electronic device, advantages of the present application include that the current consumption of the battery during transportation and storage can be reduced, and the power retention time of the battery can be increased, so that the user’s experience can be improved.

  • Publication number: 20230196269
    Abstract: A method for setting a shipping mode of an electronic device. The method includes the following steps: receiving a shipping instruction sent by a host computer to enter the shipping mode; and sending a shipping-mode feedback instruction to the host computer, where the shipping-mode feedback instruction is a valid-response instruction for a successful entry into the shipping mode or an invalid-response instruction for a failed entry into the shipping mode. An electronic device and a computer readable storage medium are also provided in this application. The method for setting the shipping mode, the electronic device and the computer readable storage medium can accurately feed back whether the electronic device has successfully entered the shipping mode, to avoid a problem that the electronic device not really entering the shipping mode can leave the factory due to omission, improving users' experience.

  • Patent number: 11631662
    Abstract: The present invention discloses a System on Chip, which includes a power supply pin, a ground pin, an anti-static unit and an anti-reverse connection unit, wherein the anti-static unit is connected between the power supply pin and the ground pin through the anti-reverse connection unit, the power supply pin and the ground pin of the System on Chip are connected to an external power supply; wherein, when the System on Chip is in normal operation, the anti-static unit performs ESD protection of the power supply pin through the conducted anti-static unit; whereas when the external power supply is reversely connected between the power supply pin and the ground pin of the System on Chip, the anti-reverse connection unit is cut off to prevent the reversely connected external power supply from directly connecting anode with cathode of the external power supply through the anti-static unit.
