  • CHARGING CIRCUIT OF ELECTRONIC DEVICE, AND ELECTRONIC DEVICE
    Publication number: 20220085637
    Abstract: Provided are a charging circuit and an electronic device. The charging circuit includes a first switch tube and an electro-migration suppression circuit. A first end of the first switch tube is connected to a power supply, and a second end of the first switch tube is connected to a to-be-charged battery. The electro-migration suppression circuit is electrically connected to a controlled end of the first switch tube; wherein in a condition of the power supply stopping charging the to-be-charged battery, the electro-migration suppression circuit is configured to adjust a voltage difference between the second end and the controlled end of the first switch tube by adjusting a voltage on the controlled end of the first switch tube, for reducing an electro-migration amount between the second end and the controlled end of the first switch tube.
