EMC1423/EMC1424 1°C Temperature Sensor with
Hardware Thermal Shutdown PRODUCT FEATURES Datasheet General Description Applications The EMC1423 and EMC1424 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. „ Additionally, the EMC1423 and EMC1424 provide a
hardware programmable system shutdown feature that
is programmed at part power-up via two pull-up resistor
values and that cannot be masked or corrupted through
the SMBus.
Each device provides ±1° accuracy for external diode
temperatures and ±2°C accuracy for the internal diode
temperature. The EMC1423 monitors three temperature
channels (two external and one internal). The EMC1424
monitors four temperature channels (three external and
one internal).
Resistance Error Correction automatically eliminates the
temperature error caused by series resistance allowing
greater flexibility in routing thermal diodes. Beta …
