Overview
Global Mixed-mode Technology Inc.
G762/G763 Fan Speed Controller with Linear or PWM Mode 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 G763 „ G763 has Built-in Inverter for Crystal Oscilla- tor „ SOP-8/MSOP-8 for G762 „ MSOP-10 for G763 Applications „ Notebook PC „ Industrial PC „ LAN Switch „ Servers „ Telecom equipment „ Industrial Control General Description The G762/G763 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.
It determined the current fan speed based on the fan rotation pulses and an externally supplied clock.
The desired fan speed is programmed via the SMBus.
The actual fan speed and fan status can be read via the SMBus.
Short-circuit protection is implement...
