1. General Description

2. Feature List

of the F75133S. The F75133S is following the PWM signal change of duty cycle to react related functions for

user application. For instance, the F75133S can be used to sense CPU loading for FAN speed control to cool

down the temperature of CPU surface. It also can be used to implement Over/Under-Clocking and

Over/Under-Voltage (Vcore) with higher performance/Lower power consumption. Anyway, the F75133S can be

implemented by user differential application.

between power and parts, and then they detected ∆V and capitalized the value to understand the loading

condition. Although the method is convenient and needs just a cheap resistance, but some of the accuracy

issues and power consumption problem will be the critical points. For example, the resistance will cause more

consumption and heat questions if the end-equipment needs mass current to implement. Depends on these

problems, more accuracy and more efficiency sensor chip is necessary. The F75133S will handle previous

trouble.

TURBO#、FAULT# and PME# signals for end-application, provides I2C interface for communication, the

programmable Cycle-Length of detection rise the measurement accuracy.
