Product Summary

The W83791G is an evolving version of the W83782G. Besides the conventional functions of W83782G, W83791G uniquely provides several innovative features such as speech function, ASF sensor compliant, SMBus 2.0 ARP command compatible, VID table selection trapping, and 5VID output control. An 8-bit analog-to-digital converter (ADC) was built inside W83791G. W83791G can simultaneously monitor 10 analog voltage inputs (including power VDD/5VSB monitoring), 5 fan tachometer inputs, 3 remote temperatures, and one case open detection signal.
