EMC1428
EMC1428 is Multiple Temperature Sensor manufactured by Microchip Technology.
FEATURES
Data Sheet
General Description
The EMC1428 is a high accuracy, low cost, System Management Bus (SMBus) temperature sensor. Advanced features such as Resistance Error Correction (REC), Beta pensation (to CPU diodes requiring the BJT or transistor model) and automatic diode type detection bine to provide a robust solution for plex environmental monitoring applications.
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 internal).
