1. GENERAL DESCRIPTION
W83L786NR/NG 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, 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.
W83L786NR/NG can monitor up to 3 analog voltage inputs, 2 fan tachometer inputs, and 2 remote
temperature sensors. One of the temperature inputs is connected to CPU/GPU thermal diode sensor,
and the other remote temperature sensor could be performed by either thermal diode or thermistor.
Power-on fan_set configuration offers the function to choose one of the four duty cycles, 100%, 81%,
62%, 43%, as initial fan speed. 2 sets of PWM (Pulse Width Modulation) / DC (Direct Current) fan
output for SMART FAN
TM control – “Thermal CruiseTM” mode and “SMART FANTM II “mode. Under
“Thermal Cruise
TM “mode, temperatures of GPU and the system can be maintained within specific
programmable ranges under the hardware control. Under “SMART FAN
TM II” mode, the fan could be
operated at the lowest possible speed for minimum acoustic noise, and the dynamic intelligent fan
management could create the most quiet system environment and stable working performance. An 8-
bit analog-to-digital converter (ADC) is built inside W83L786NR/NG. As for warning mechanism,
W83L786NR/NG provides four pure hardware event pins for independent warning signals:
VOLTAGE_FAULT#, FAN_FAULT#, TEMP_FAULT#, and INT#. All threshold values could be set for
system protection without any timing delay. One bit power-on address selection is used to decide the
address of the W83L786NR/NG over I
2C serial bus interface. W83L786NR/NG also provides up to 7
optional multifunctional GPIO. W83L786NR/NG is powered by 3.3V.
Through the application software or BIOS, the users can read all the monitored parameters of system
from time to time. A pop-up warning can also be activated when the monitored item is out of the
proper / preset range. The application software could be Winbond's Hardware Doctor
TM, IntelTM LDCM
(LanDesk Client Management), or other management application software. Also the users can set up
the upper and lower limits (alarm thresholds) of these monitored parameters and activate one
programmable interrupts. For the spacing saving consideration of the Graphic cards and Notebook
system, W83L786NR/NG is 20-pin SSOP package.
