HV7800 Datasheet (Supertex) - High Side Current Monitor

HV7800, High Side Current Monitor

The HV7800 high side current monitor IC transfers a highside current measurement voltage to its ground referenced output with an accurate voltage gain of one.

The measurement voltage typically originates at a current sense resistor which is located in a “high side” circuit, such as the positive supp
