  • Reverse current prevention for FET used as reverse polarity protection device
    Patent number: 10778019
    Abstract: A battery reverse polarity protection circuit is disclosed. The battery reverse polarity protection circuit includes a field effect transistor (FET) coupled to a control circuit. The FET is configured to transmit an input voltage from a normal-polarity-connected battery to an output terminal, and block the input voltage from a reverses polarity-connected battery to the output terminal. The control circuit is coupled to the input terminal, the output terminal, and a common terminal and is configured to detect, during transmission of the input voltage from the normal-polarity-connected battery to the output terminal, that the input voltage is less than an output voltage, indicating onset of an abnormal operating mode, and turn off the FET to prevent the output voltage from being affected by the input voltage during the abnormal operating mode.
