Datasheet

PRODUCT FEATURES

GENERAL DESCRIPTION

FEATURES

Supports two External Temperature Diodes

The EMC1043 is a family of System Management Bus

(SMBus) temperature sensors that monitors three

temperature zones, one internal diode and two

externally connected diodes, for PC and embedded

environments. The EMC1043 includes beta

compensation circuitry to correct for variation in the beta

of measurement transistors. Other extended features

include resistance error correction and ideality factor

configuration to eliminate major sources of temperature

measurement error.¹

An added feature to the EMC1043 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.
