EMC1412

EMC1412 Multiple Channel 1°C Temperature Sensor with Beta Compensation Features Programmable SMBus Address Support for diodes requiring the BJT/transistor model including advanced processor geometries Automatically determines external diode type and optimal settings Resistance Error Correction External Temperature Monitor: - ±1°C Maximum Accuracy (+20°C < TDIODE < +110°C) - 0.125°C resolution - Supports up to 2.2 nF Diode Filter Capacitor Internal Temperature Monitor: - ±1°C Accuracy - 0.125°C Resolution 3.3V Supply Voltage Programmable temperature limits for ALERT and THERM Available in small 8-pin 2 mm x 3 mm TDFN RoHS compliant package Available in small 8-pin MSOP RoHS compliant package Applications Notebook Computers Desktop Computers Industrial Embedded Applications Package Type Description The EMC1412 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) and automatic diode type detection combine to provide a robust solution for complex 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 d...
