EMC1053
1°C Triple Temperature
Sensor with Resistance
Error Correction &
Hotter of Two Zones
PRODUCT FEATURES
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
