W83L786NR Product details

GENERAL DESCRIPTION
W83L786NR/NG is an evolving product of W83L785R -- Winbonds most popular hardware monitoring IC, and intelligent fan controlling IC. Specifically designed for the graphic cards and barebone /mini systems, W83L786NR/NG 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
    ■ Measure the temperature with high accuracy.
    ■ One thermal diode sensor (current mode) connected to CPU/GPU and one remote
        sensor either by thermal diode (current mode) or thermistor.
    ■ Programmable hysteresis and setting points (alarm thresholds) for all monitored
        items.
Voltage
    ■ 3 voltage sensor inputs.
        --- Typically for Vcore, RAM, etc.
Fan
    ■ 3D/2D application being used and transferring fan set to the most appropriate fan
        speed control.
    ■ Fan set: power on configuration for fan speed at four rotation rate levels at 43%, 62%,
        81%, and 100% duty cycle.
    ■ Two DC/PWM fan output control.
    ■ SMART FANTM function compliant.
Actions Enabling
    ■ Total up to 2 sets of fan speed monitoring and controlling.
    ■ Issue FAN_FAULT#, VOLTAGE_FAULT#, TEMP_FAULT#, and INT# signals to
        activate system protection.
    ■ Warning signal pop-up in application software.
General
    ■ Interface: I²C / SMBus control.
    ■ 1 bit I2C address selection.
    ■ Up to 7 GPIOs.
    ■ Winbond hardware monitoring application software (Hardware DoctorTM) support
        Windows 95 / 98 / 2000 / XP and Windows NT 4.0 / 5.0.
    ■ 3.3V VCC operation.
Package
    ■ 20-pin SSOP (209mil).
