Description
The EMC1412 is a high accuracy, low cost, System Management Bus (SMBus) temperature sensor. Advanced Features such as Resistance Error Correction (REC), Beta pensation (to support CPU diodes requiring the BJT/transistor model) and automatic diode type detection bine to provide a robust solution for plex 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 pensation eliminates temperature errors caused by low, variable beta transistors mon 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,...
