Description

The TSC102 measures a small differential voltage

on a high-side shunt resistor and translates it into

a ground-referenced output voltage.

The TSC102 is rugged against abnormal

conditions on the input pins: Vp and Vm can

withstand up to 60 V in case of voltage spikes, as

little as -16 V in case of reversed battery, and up

to 4 kV in case of electrostatic discharge.

The device’s wide input common-mode voltage

range, low quiescent current and tiny TSSOP8

packaging enable use in a wide variety of

applications (also available in SO-8 package).

In addition to the current sensing amplifier, the

TSC102 offers a fully accessible amplifier for

output signal conditioning.

The input common-mode and power supply

voltages are independent. The common-mode

voltage can range from 2.8 to 30 V in operating

conditions.

The device’s overall current consumption is lower

than 420 µA.
