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 to 30 V
■ Wide common-mode surviving range:
    -32 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 to 125°C operating temperature range
■ Internally fixed gain: 20 V/V, 50 V/V
■ EMI filtering
   
Applications
