Product overview

Description

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

The TSC1021 has been specifically designed for automotive conditions: load-dump protection up to 60 V, reverse-battery protection up to -32 V, ESD protection up to 4 kV and internal filtering for EMI performance.

Input common-mode and power supply voltages are independent: the common-mode voltage can range from 2.8 to 30 V in operating conditions and up to 60 V in absolute maximum ratings while the TSC1021 can be supplied by a 5 V independent supply line.

The TSC1021 is housed in a tiny TSSOP8 package and integrates a buffer that provides low impedance output to ease interfacing and avoid accuracy losses. The overall device current consumption is lower than 300 µA.

  • All 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: ICCmax = 300 µA
    • -40 °C to 125 °C operating temperature range
    • Internally fixed gain: 20 V/V, 50 V/V
    • EMI filtering
