GENERAL DESCRIPTION
W83L784R/G is an evolving product of W83782D/G --- Winbonds most popular hardware status monitoring IC. Specifically designed for the Notebook system, W83L784R/G 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.
General
? I2CTM serial bus interface
? IntelTM LDCM (DMI driver 2.0) support
? AcerTM ADM (DMI driver 2.0) support
? Winbond hardware monitoring application software (Hardware DoctorTM ) support, for both Windows 95/98
? Meet WfM 2.0 (Wired for Management) spec.
? 5V Vcc operation
Package
? 20-pin SSOP (209mil)
