EMC1428
1°C Multiple Temperature Sensor with HW
Thermal Shutdown & Hottest of Thermal Zones
PRODUCT FEATURES Data Sheet General Description Features The EMC1428 is a high accuracy, low cost, System
Management Bus (SMBus) temperature sensor.
Advanced features such as Resistance Error Correction
(REC), Beta Compensation (to CPU diodes requiring the
BJT or transistor model) and automatic diode type
detection combine to provide a robust solution for
complex environmental monitoring applications. — triggers dedicated SYS_SHDN pin
— hardware configured range 65°C to 127°C in 1°C steps
— cannot be disabled or modified by software
Additionally, the EMC1428 provides a hardware
programmable system shutdown feature that is
programmed at part power-up via a single TRIP_SET
voltage channel that cannot be masked or corrupted
through the SMBus.
The EMC1428 provides ±1° accuracy for external diode
temperatures and ±2°C accuracy for the internal diode
temperature. The device monitors up to eight
temperature channels (up to seven external and one …
