EMC1412
Multiple Channel 1°C Temperature Sensor with
Beta Compensation
PRODUCT FEATURES Data Sheet General Description Applications The EMC1412 is a high accuracy, low cost, System
Management Bus (SMBus) temperature sensor.
Advanced features such as Resistance Error Correction
(REC), Beta Compensation (to support CPU diodes
requiring the BJT/transistor model) and automatic diode
type detection combine to provide a robust solution for
complex environmental monitoring applications.  The EMC1412 monitors two temperature channels (one
external and one internal). 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 the 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 …
