Description
W83L786G-A is an evolving product of W83L785R -- Winbond's most popular hardware monitoring IC, and intelligent fan controlling IC. Specifically designed for the graphic cards and barebone / mini systems, W83L786G-A can be used to monitor several critical hardware parameters of the system, including voltages, fan speeds, and temperatures, which are very important for the system to work stably and properly.
Specifications and features
Monitoring Items
Temperature
■ Measure the temperature with high accuracy.
■ Two thermal diode sensor inputs (current mode) and one thermistor sensor input.
■ Programmable hysteresis and setting points (alarm thresholds) for all monitored items.
Voltage
