HV7801 Datasheet (Supertex) - High Side Current Monitor

HV7801, High Side Current Monitor

The HV7801 high side current monitor IC transfers a highside current measurement voltage to its ground referenced output with a voltage gain of five.

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