G764 - Fan Speed Controller

Description

The G764/G765 is a single chip solution for fan speed control.

It can be directly connected to the fan and performs close-loop or open-loop control.

And there are two modes, PWM and linear, to drive the fan.

Features

  • SMBus Interface.
  • Linear or PWM Mode Speed Control.
  • Open or Close Loop Fan Speed Control.
  • Supply Voltage Range 3V~5.5V.
  • ADD0 Pin to Select 3 Different SMBus Addresses.
  • SMBus Alert # for G765.
  • G765 has Built-in Inverter for Crystal Oscilla- tor.
  • Internal 32kHz clock generator, +/- 3% accuracy.
  • SOP-8/MSOP-8 for G764.
  • MSOP-10 for G765 General.
