  • Smart electronic switch
    Patent number: 11527881
    Abstract: A circuit includes a monitor circuit. The monitor circuit includes a nonlinear functional unit configured to receive a current sense signal and to generate a power signal representing the power of the current sense signal. The circuit further includes a first filter configured to receive the power signal and to generate a first filtered signal and a second filter configured to receive an input signal that depends on the current sense signal and to generate a second filtered signal. A comparator circuit is configured to receive the first filtered signal and the second filtered signal and to compare the first filtered signal with a first threshold value and the second filtered signal with a second threshold value. The protection signal is indicative of whether the first filtered signal exceeds the first threshold value or the second filtered signal exceeds the second threshold value.
