Description

The HV7800 is a high side current monitor IC, which senses the voltage across an external current sense resistor located in the power or "high" side of the circuit and translates this voltage to a ground referenced circuit at a gain of one.

The HV7800 has a wide operating range of 3V-450VDC, which enables its use in DC power systems of 12V/24V/ 48V, and in AC systems operating at voltages from 85VAC to 265VAC.

The fast response time of the HV7800 allows use of this current monitor in the feedback loop of a switching power supply or in LED driver applications.
