High side current sense high voltage op amp

Datasheet

- production data

Features

 Independent supply and input common-mode

voltages

 Wide common-mode operating range: 2.9 V to

70 V in single-supply configuration, -2.1 V to

65 V in dual-supply configuration

 Wide common-mode surviving range: -16 V 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: I

CC max = 360 µA

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

100 V/V

 Buffered output

Applications

 Wireless battery chargers

 Chargers for portable equipment

 Precision current sources

 Wearable

Description

The CS70 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.

The input common-mode and power-supply

voltages are independent. The common-mode

voltage can range from 2.9 V to 70 V in the single-

supply configuration or be offset by an adjustable

voltage supplied on the Vcc- pin in the dual-

supply configuration.

With a current consumption lower than 360 µA

and a virtually null input leakage current in

standby mode, the power consumption in the

applications is minimized.
