Overview
W83L785R WINBOND H/W MONITORING IC FOR NOTEBOOK 1.
GENERAL DESCRIPTION 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) was built inside W83L785R.
The W83L785R can monitor 4 analog voltage inputs, 2 fan tachometer inputs, 2 remote temperature sensors.
The remote temperature sensing can be performed by thermistors, or 2N3904 NPN-type transistors, or connected from IntelTM Deschutes CPU thermal diode output.
The W83L785R provides 2 PWM (pulse width modulation) outputs for the fan speed control.
Also the W83L785R provides: SMI#, OVT#, Temp fault, GPIO signals for system protection events; I2CTM serial bus interface.
