H/W Monitor for Graphic Card, NB and IA

W83L786G is specifically designed for the graphic cards and bare bone / mini systems, and can be used to monitor several critical hardware parameters of the system, including voltage, fan speed, and temperature, which are very important for the system to work stably and properly.

W83L786G provides 1 set of VID to detect CPU voltage and could be used for overcolcking. W83L786G has 5 analog voltage inputs, 2 fan tachometer inputs, and 3 remote temperature sensor inputs. Power-on fan_set configuration offers the function to choose one of the four duty cycles, 100%, 81%, 62%, 43%, as initial fan speed. 2 sets of PWM (Pulse Width Modulation) / DC (Direct Current) fan outputs are provided for SMART FAN^TM control – “Thermal Cruise^TM” mode and “SMART FAN^TM II“ mode. An 8-bit analog-to-digital converter (ADC) is built inside W83L786G. As for warning mechanism, W83L786G provides four pure hardware event pins for independent warning signals. All threshold values could be set for system protection without any timing delay. One bit power-on address selection is used to decide the address of the W83L786G over I²C serial bus interface. W83L786G also provides up to 14 optional multifunctional GPIO. W83L786G is powered by 3.3V, and is 28-pin SSOP package.
