描述 Description

The F75334DG is a series of hardware monitoring & intelligent fan controlling IC. The F75334DG integrated Hardware Monitor, PWM Loading Gauge, VID controller and GPIO functions inside. Part of the Hardware Monitor is for system protection including 6 channels voltage monitor, 4 sets dual current sources temperature sensor, 3 sets fan speed sensor and controller. Besides, F75334DG supports AMDSI interface for AMD series CPU temperature reading & Intel PECI/SST interface. PWM Loading Gauge is sensing the PWM signal change of duty cycle to react related functions for over/under-clocking application. VID controller is the dynamic voltage ID controller chip to provide the advanced CPU voltage programming when over/under clocking.  The dynamic VID spec. is for new generation Intel/AMD CPU and also compatible to VRM9.0/VRM10.0/VRM10.X /VRM11.0 spec. Additionally, the F75334DG provides easy voltage sensor input/output (VSI/VSO) function to sense Vcore voltage, then output the offset voltage for over/under voltage change use.  Otherwise, F75334DG provides 21 GPIO pins for flexible application.(1)The F75334DG supports three main features for system protection, system over/under-clocking and dynamic voltage ID control. The F75334DG can easily save the total cost and improve system performance. The F75334DG supports 2 wire I2C interface, packaged in 48-pin LQFP green package and powered by 3.3V.(1)(1)
