General Description

The HV7802 high side current monitor IC contains a transconductance amplifier which translates a high side current measurement voltage into an output current with resistor programmable transconductance gain. An optional second resistor transforms this output current into an output voltage with an overall voltage gain set by the ratio of the two resistors.

Features

► Supply voltage 8V to 450V

► Configurable as a current or voltage output device

► Maximum sense amplifier offset of 15mV

► Max VSENSE of 500mV

► Fast rise and fall time, from 700ns to 2.0µs

► Maximum quiescent current of 50µA

Applications

► SMPS current monitor

► Battery current monitor

► Motor control
