PRODUCT FEATURES

EMC1053

1°C Triple Temperature

Sensor with Resistance

Error Correction &

Hotter of Two Zones

General Description

The EMC1053 is a System Management Bus (SMBus)

temperature sensor that monitors three temperature

zones, one internal diode and two externally connected

diodes, for PC and embedded environments. The

EMC1053 includes resistance error correction and

ideality factor configuration to eliminate major sources of

temperature measurement error.1

An added feature to the EMC1053 is a function that

automatically compares the two external temperature

zones and reports the hotter of the two temperatures.

Selectable conversion rates and standby mode support

low-power operation. The temperature measurement

ranges support two data ranges (and formats), -64°C to

+127°C and -64°C to +191°C.

Applications

Desktop and Notebook Computers
