4X Linear Fan Driver for 12V DC Fan

Features

General Description

VO Follows 4.0 Times of VSET

The G9941 is a high performance positive voltage

0.5V Dropout @ 0.5A

Over Current and Over Temperature Protection

Enable Pin

100µA Quiescent Current in Shutdown

Power TO-252-5, SOP-8 with power pad

Package

regulator designed for use in applications requiring

very low dropout voltage at up to 0.5 Amps. The

G9941 VO output voltage follows the 4.0 times of

VSET voltage until it reaches VIN voltage. The VSET

voltage must be larger than 1V to guarantee VO 4.0

times of VSET. An enable pin further reduces power

dissipation while shut down. The G9941 provides ex-

cellent regulation over variations in line, load and

temperature.

Applications

Notebook Computer Fan Driver

Projector Cooling Fan

Battery Powered Systems

Motherboards

The G9941 is available in the power TO-252-5 and

SOP-8 with power pad package.
