GENERAL DESCRIPTION

W83L786R/G 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, W83L786R/G 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.

FEATURES

Monitoring Items
Temperature
â– Measure the temperature with high accuracy.
â– Two thermal diode sensor inputs (current mode) and one thermistor sensor input.
â– Programmable hysteresis and setting points (alarm thresholds) for all monitored items.

Voltage

â– 5 voltage sensor inputs.
--- Typically for Vcore, +3.3V (Power), RAM, AGPâ€¦etc.
â– Five VID bits Intel VRM 9.0 compliant to set Vcore voltage for GPU overclocking.
â– Watch Dog Timer with INT# output for overclocking failure recovery. (VID pins output control is also cleared by this INT#).
â– Power on configuration for Vcore input.

Fan

â– 2 sets of fan speed monitoring and controlling.
â– 3D/2D application being used and transferring fan set to the most appropriate fan speed control.
â– Fan set: power on configuration for fan speed at four rotation rate levels at 43%, 62%, 81%, and 100% duty cycle.
â– Two DC/PWM fan output control.
â– SMART FANTM function compliant.

Actions Enabling

â– Issue FAN_FAULT#, VOLTAGE_FAULT#, TEMP_FAULT#, and INT# signals to activate system protection.
â– Warning signal pop-up in application software.

General

â– Interface: IÂ²C / SMBus control.
â– 1 bit I2C address selection.
â– Up to 14 GPIOs.
â– Winbond hardware monitoring application software (Hardware DoctorTM) support Windows 95 / 98 / 2000 / XP and Windows NT 4.0 / 5.0.
â– 3.3V VCC operation.

Package

â– 28-pin SSOP (209mil).
