W83L771AWG/W83L771ASG
1. GENERAL DESCRIPTION
The W83L771AWG/ASG, a one remote and one local temperature sensor with 2 temperature alert
outputs and with 2-wire System Management Bus (SMBus^TM) serial interface, is Nuvoton hardware
monitoring IC specifically designed for PC, notebook and any embedded environments. The
W83771AWG/ASG uses Ideality Factor Configuration to eliminate temperature measurement error.
The remote temperature sensor input can be connected to thermal diode or transistor such as 2N3904.
A 10-bit plus sign ADC (Analog to Digital Converter) with 0.125C resolutions is built inside
W83L771AWG/ASG to convert the monitored temperature value. Programmable conversion rates and
stand-by mode support low-power operation.
The W83L771AWG/ASG is a high temperature accuracy, low-power consumption, SMBus^TM serial
interface IC, which is available in 8-pin, TSSOP (MSOP) and SOP package, with the working voltage of
3.3 V ±10%.
