ABSTRACT:
This on/off power detector includes an input connected directly to a power source and input connected to the power source through a switch. The detector compares voltages on the two inputs to produce an output signal when the voltage on the switched input drops a predetermined amount below the voltage on the unswitched input, which is indicative of the switch being open. The detector is strobed on and off and only compares the input voltages to provide the output signal when it is in its strobed on condition.
