W83L785R Overview
W83L785R is a condensed product of W83L785R --- Winbond's most popular hardware monitoring IC for notebook. Specifically designed for the graphic cards and notebook systems, W83L785R 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. An 8-bit analog-to-digital converter (ADC)...
