SC310

High-Side Current-Sense Amplifier

with Low Impedance Voltage Output

POWER MANAGEMENT

Description

Features

The SC310 is a high-side current sense amplifier ideal for

any application where precision current monitoring is

needed. Possible uses include battery-powered products

such as cellphones and notebooks, as well as industrial

and data acquisition applications. The wide 2.7V to 25V

common mode input range is independent of supply range,

providing complete flexibility in battery sensing applica-

tions.

ꢀ

Three gain versions (20V/V, 50V/V, 100V/V)

1% typical accuracy

Buffered low impedance voltage output

Industrial temperature range (-40°C to +125°C)

Small, lead-free SOT23-6 Package

The Current-Sense Amplifier offers three gain versions,

SC310A (gain 20 V/V), SC310B (gain 50 V/V) and

SC310C (gain 100 V/V). An external shutdown pin

(SHDN) enables turn off for the IC. A buffered output

with low impedance renders the overall gain immune to

load resistance. Output range is from 0V to Vcc - 1.7V.

Applications

ꢀ

Notebook and Tablet PCs

Data Acquisition

Battery Packs

Charging Applications

Industrial and Embedded Applications

Other features include tiny SOT-23-6 packaging, very low

supply current, and wide supply voltage range (3V to 25V).

The SC310 is rated for operation over the Industrial Tem-

perature range (-40°C to +125°C).
