H/W Monitor for Graphic Card, NB and IA

W83L784G is specifically designed for the Notebook system, and can be used to monitor several critical hardware parameters of the system, including power supply voltage, fan speed, and temperature, 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 W83L784G. W83L784G has 4 analog voltage inputs, 2 fan tachometer inputs, one on-chip internal temperature sensor and 2 remote temperature sensor inputs. W83L784G provides 2 PWM (pulse width modulation) outputs for fan speed control and supports Nuvoton`s Thermal Cruise^TM mode, which helps to keep the temperature in the specific programmable temperature range. W83L784G provides power good reset for 3V and 5V; power down mode for power saving; fault pin for necessary H/W shutdown control; SMI#, OVT# signals for system protection events; I²C serial bus interface. The package is 20-pin SSOP, and the working voltage is 5V.
