HighAccuracy Thermal Monitor

with I2C Interface

Features

General Description

The uP1905 is a high-accuracy thermal monitor forDC/DC Work with 3V~5.5V Input Voltage

converter.Three temperature sensing inputs are available

for monitoring temperature of the system.

Three Temperature Sensing Inputs TM1~TM3
