General Description

The  G761  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  im-plemented  to  prevent  damages  to  the  fan  and  the  IC itself.
