ABSTRACT:
A power shutdown circuit includes an electronic latch circuit connected in series with a monitored power supply and comparator input and power terminals. The output terminal of the comparator is coupled to the control terminal of the latch. When a monitored signal magnitude crosses a threshold, the comparator provides a control signal which renders the latch nonconductive. A main switch device also connected to an output of the latch responds to the nonconductive state thereof to remove power from an electrical load.
