GENERAL DESCRIPTION
The SGM8196 is a high voltage, high-side current-sense amplifier that operates from 2.7V to 5.5V single supply. The device also features a wide common mode voltage range from 2.9V to 70V in single-supply operation or (-VS) + 2.9V to (-VS) + 70V in dual-supply operation. And the input common mode voltage is independent with the power supply voltage.
The SGM8196 is designed to convert the measured small differential voltage across the high-side shunt resistor to the output voltage referred to GND. There are four different gains for SGM8196: 20V/V, 25V/V, 50V/V or 100V/V. The current consumption of the device is only 320μA and almost no leakage current flows into the device in standby mode, which minimizes power consumption in applications.
