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.  
±1°C Accuracy (40°C to 80°C)  
0.125°C Resolution  
Ideality Factor Configuration  
Accepts 2200pF Cap Across External Diodes for Noise
