Description

W83L771W/G, a 2-channel temperature sensor with a 2-wire System Management Bus (SMBus^TM) serial interface, is Winbond hardware monitoring IC specifically designed for notebook applications. W83L771W/G has an on-chip thermal sensor and a remote temperature sensor input with high accuracy. The remote temperature sensor input could be connected to thermal diode or transistor such as 2N3904. A 10-bit plus sign ADC (Analog to Digital Converter) with 0.125 resolutions is built inside W83L771W/G to convert the monitored temperature value.

W83L771W/G is a high temperature accuracy, low-power consumption, SMBus^TM serial interface IC, which is available in 8-pin, TSSOP package, and the working voltage is 3.3 V ±10%.
