General Description
The HV7801 high side current monitor IC transfers a high side current measurement voltage to its ground referenced output with an accurate voltage gain of fi ve. The measurement voltage typically originates at a current sense resistor which is located in a “high side” circuit, such as the positive supply line.

Voltage output device
Typical gain 5±1%
Max V_SENSE 500mV
Fast rise and fall times, 700ns to 2µs
Maximum quiescent current 50µA

APPLICATIONs
SMPS current monitor
Battery current monitor
