Applications

Description

The TSC101 measures a small differential voltage

on a high-side shunt resistor and translates it into

a ground-referenced output voltage. The gain is

internally fixed.

Wide input common-mode voltage range, low

quiescent current, and tiny SOT23 packaging

enable use in a wide variety of applications.

Input common-mode and power supply voltages

are independent. Common-mode voltage can

range from 2.8V to 30V in operating conditions

and up to 60V in absolute maximum ratings.

Current consumption lower than 300µA and wide

supply voltage range allow to connect the power

supply to either side of the current measurement

shunt with minimal error.
