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 T_amb= 25 °C

±2.3 mV for -40 °C < T_amb < 125 °C

Maximum total output voltage error:

±1.5 % for T_amb= 25 °C

±2.5 % for -40 °C < T_amb < 125 °C

Maximum variation over temperature:

dV_os/dT = 8 µV/°C

dV_out/dT = 100 ppm/°C

Low current consumption: I_CCmax = 300 µA

-40 °C to 125 °C operating temperature range

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