TSC1021 - High-side current sense amplifier

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 temperatur.
