Fan Speed PWM Controller

General Description

G760A

Features

^ꢀConstant Fan Speed Control

^ꢀPWM control for stable operation

^ꢀBuild-in MOSFET switch

^ꢀSMBus interface

G760 is a single chip solution for fan speed control,

packaged in a space saving SO-8 package. It con-

nects directly to the fan and performs closed-loop

control of the fan speed. The only external compo-

nent required is a 10µF capacitor. It determined the

current fan speed based on the fan rotation pulses

and an externally supplied clock. It uses pulse width

modulation (PWM) method and an on-chip

MOSFET to control the fan speed to 2% of the

programmed speed. The desired fan speed is pro-

grammed via the SMBus. The actual fan speed and

fan status can be read via the SMBus. Short-circuit

protection is implemented to prevent damages to

the fan and this IC itself. An On/Off control pin is

also provided.
