Device Overview

Summary

NOT RECOMMENDED FOR NEW DESIGN - use EMC1413 as an alternative

The EMC1053 is an I2C / 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 error1.

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.

1. Patents pending.
