G765 - Fan Speed Controller

Download the G765 datasheet PDF. This datasheet also covers the G764 variant, as both devices belong to the same fan speed controller family and are provided as variant models within a single manufacturer datasheet.

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.
