EMC1422 1°C Temperature Sensor with
Hardware Thermal Shutdown PRODUCT FEATURES Datasheet General Description Applications The EMC1422 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 including 45nm,
65nm and 90nm processors) and automatic diode type
detection combine to provide a robust solution for
complex environmental monitoring applications. „ Additionally, the EMC1422 provides 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. „
