    Abstract: A charging protection device comprises a universal serial bus (USB) interface, a resistance circuit, a detection circuit and a control circuit. The universal serial bus interface includes a configuration channel. The resistance circuit includes a pull-down resistor coupled between the configuration channel and a ground GND. The detection circuit is configured to detect an abnormal charging condition. The detection circuit generates an abnormal signal when the abnormal charging condition occurs. The control circuit is coupled to the detection circuit and configured to change a voltage value on the pull-down resistor to be out of a preset voltage range according to the abnormal signal.

    Abstract: A boost converter and a power control method thereof. The boost converter includes an inductor, a first switch unit, a second switch unit, a discharging loop and a detecting circuit. The inductor is electrically connected to a power input end. The first switch unit is electrically connected between the inductor and ground. The second switch unit is electrically connected between the inductor and an output end. The discharging loop is connected with the inductor in parallel and includes a third switch unit. The detecting circuit is used to detect a discharging value of the inductor. When the discharging value exceeds a threshold value, the third switch unit is turned on, and the inductor releases energy via the discharging loop.
