EMC1413 / EMC1414
Multiple Channel 1°C
Temperature Sensors with
Beta Compensation
PRODUCT FEATURES
Datasheet
General Description
The EMC1413 / EMC1414 are high accuracy, low cost,
System Management Bus (SMBus) temperature
sensors. Advanced features such as Resistance Error
Correction (REC), Beta Compensation (to support CPU
diodes requiring the BJT/transistor model including
45nm, 65nm and 90nm processors) and automatic
diode type detection combine to provide a robust
solution for complex environmental monitoring
applications.
The EMC1413 monitors three temperature channels and
the EMC1414 monitors four temperature channels. It
provides ±1°C accuracy for both external and internal
diode temperatures.
Resistance Error Correction automatically eliminates the
temperature error caused by series resistance allowing
greater flexibility in routing thermal diodes. Beta
Compensation eliminates temperature errors caused by
low, variable beta transistors common in today's fine
geometry processors. The automatic beta detection
feature monitors each external diode/transistor and
determines the optimum sensor settings for accurate
temperature measurements regardless of processor
technology. This frees the user from providing unique
sensor configurations for each temperature monitoring
application. These advanced features plus ±1°C
measurement accuracy provide a low-cost, highly
flexible and accurate solution for critical temperature
monitoring applications.
