Description

The TSC1021 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage.

Features

• Wide common-mode operating range

independent of supply: 2.8 V to 30 V

• Wide common-mode survival range: -32 V to

60 V (reversed battery and load-dump

conditions)

• Maximum input offset voltage:

- ±1.5 mV for Tamb = 25 °C

- ±2.3 mV for -40 °C < Tamb < 125 °C

• Maximum total output voltage error:

- ±1.5 for Tamb = 25 °C

- ±2.5 for -40 °C < Tamb < 125 °C

• Maximum variation over temperature:

- dVos/dT = 8 µV/°C

- dVout/dT = 100 ppm/°C

• Low current consumption: ICC max = 300 µA

• -40 °C to 125 °C operating temperature

range

• Internally fixed gain: 20 V/V, 50 V/V

• EMI filtering

Applications
