TSC103中文资料意法半导体数据手册PDF规格书

Description

The TSC103 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The gain is adjustable to four different values from 20 V/V up to 100 V/V by two selection pins.

Wide input common-mode voltage range, low quiescent current, and tiny TSSOP8 packaging enable use in a wide variety of applications.

Features

■ Independent supply and input common-mode

voltages

■ Wide common-mode operating range:

2.9 to 70 V in single-supply configuration

-2.1 to 65 V in dual-supply configuration

■ Wide common-mode surviving range:

-16 to 75 V (reversed battery and load-dump

conditions)

■ Supply voltage range:

2.7 to 5.5 V in single-supply configuration

■ Low current consumption: ICC max = 360 µA

■ Pin selectable gain: 20 V/V, 25 V/V, 50 V/V or

100 V/V

■ Buffered output

Applications

■ Automotive current monitoring

■ DC motor control

■ Photovoltaic systems

■ Battery chargers

■ Precision current sources

■ Current monitoring of notebook computers

■ Uninterruptible power supplies

■ High-end power supplies
