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.

Features

■ Independent supply and input common-mode voltages

■ Wide common-mode operating range: 2.8 to 30 V

■ Wide common-mode surviving range: -0.3 to 60 V (load-dump)

■ Wide supply voltage range: 4 to 24 V

■ Low current consumption: ICC max = 300 µA

■ Internally fixed gain: 20 V/V, 50 V/V or 100 V/V

■ Buffered output

Applications

■ Automotive current monitoring

■ Notebook computers

■ DC motor controls

■ Photovoltaic systems

■ Battery chargers

■ Precision current sources
