General Description
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 supply line.

Features
► Supply voltages from 8V to 450V
► Voltage output device

► Max VSENSE 500mV
► Fast rise and fall time, 700ns to 2.0µs
► Maximum quiescent current 50µA
► 5-Lead SOT-23 Package

Applications
► SMPS current monitor
► Battery current monitor
