Abstract: Embodiments of this application relate to the field of power supply system technologies, and provide a charging protection circuit, a driving method, a chip, a package structure, and an electronic device, to provide a charging protection circuit with stable bi-directional protection effect. The charging protection circuit includes a first switching transistor and a pull-up circuit. For example, the first switching transistor is a bi-directional HEMTs device, and includes a first drain electrode, a second drain electrode, a first gate electrode, and a substrate electrode. The first drain electrode is configured to receive a signal from the second drain electrode, the second drain electrode is configured to receive a signal from the first drain electrode, and the first gate electrode is configured to control the first switching transistor to be turned on or turned off.
