EMC1043
1В°C Triple Temperature
Sensor with Beta
Compensation and
Hotter of Two Zones
PRODUCT FEATURES Datasheet General Description Features 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), -64В°C to
+127В°C and -64В°C to +191В°C. В„
