  • Patent number: 12002801
    Abstract: This application relates to a charging protection circuit. The charging protection circuit implements overcurrent protection by using a four-terminal NMOS switching transistor. In the solution provided in this application, floating management is performed on a Sub port of the four-terminal NMOS switching transistor. Specifically, when the four-terminal NMOS switching transistor is turned on, potential of the Sub port is pulled up, to avoid an excessively large internal resistance of the four-terminal NMOS switching transistor caused by an excessively large voltage between the Sub port and a drain of the four-terminal NMOS switching transistor. In addition, this application further provides a charging circuit and an electronic device.

  • Patent number: 11990746
    Abstract: An apparatus detects complex time-variant electromagnetic disturbances resulting from a high-altitude nuclear electromagnetic pulse (EMP) or solar storm. The device relies on a circuit (104, 1301) to monitor the input power lines (301, 401, 501) for sustained conducted electrical disturbances associated with the E3 phase of an EMP or solar storm. A separate circuit (105, 1302) monitors the power lines and the ambient environment (503) for transient electromagnetic pulse disturbances associated with the E1 and E2 phases of an EMP. When sustained electrical disturbances or transient electromagnetic pulse disturbances are detected, the apparatus provides a visual alarm (603. 609), audible alarm (608), and discrete indication signal (607) that can be used to disconnect (702) or redirect the flow of electrical power.
