GENERAL DESCRIPTION
W83L784R is an evolving product of W83782D --- Winbonds most popular hardware status monitoring IC. Specifically designed for the Notebook system, W83L784R can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds, and temperatures, which are very important for a high-end Notebook system to work stably and properly.

FEATURES
Monitoring Items
• 2 thermal inputs from remote thermistors or 2N3904 NPN-type transistors or PentiumTM II (Deschutes) thermal diode output
• One on-chip temperature detection
• 4 voltage inputs
    --- typical for Vcore, +3.3V, +5V, Battery
• 2 sets of fan speed control and fan speed monitoring input
• WATCHDOG comparison of all monitored values
• Programmable hysteresis and setting points (alarm thresholds) for all monitored items

Actions Enabling
• Issue fan fault signal as fans are abnomally stopped
• Issue battery low signal as bettery voltage is abnomally out of range
• 2 PWM (pulse width modulation) outputs for fan speed control to support " Thermal CruiseTM " or " Speed CruiseTM "
    --- Automatically maintain the CPU or system in the specific temperature or keep the fans in the specific speed under the H/W control
• Issue SMI#, OVT#, GPO to activate system protection
• PWR_DN# setting for the Power down mode
• Warning signal pop-up in application software

Power Good
• Issue RESET# outputs as the Power Good signal when 3V and 5V rise across a reset threshold.
