ABSTRACT:
A comparator for comparing a first current proportional to an input voltage against a relatively constant reference current produced by a bandgap reference circuit. The comparator includes hysteresis whereby the response of the comparator is sharpened at the switching points. The comparator is particularly useful in combination with a switch coupling an input voltage source to a load. When the input voltage exceeds a predetermined level the first current exceeds the reference current. The comparator responds sharply and produces a signal disabling the switch and maintaining it shut off until the input voltage decreases below the predetermined level.
