GENERAL DESCRIPTION
W83L784R/G is an evolving product of W83782D/G --- Winbond's 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. An 8-bit analog-to-digital converter (ADC) is built inside W83L784R/G. The W83L784R/G provides 2 PWM (pulse width modulation) outputs for the fan speed control to support the S Thermal CruiseTM T system, which can maintain the CPU or system in the specific programmable temperature under the hardware control. Another Fan speed control mode is SSpeed CruiseS to keep the fan operating in the specific RPM. On the other hand, the W83L784R/G provides low active outputs such as fan fault and Battery low which could issue the hardware warning signals when the fan speed or battery voltage drop out of the preset range.
