EMC1183

EMC1183 Triple Channel 1°C Temperature Sensor with Beta Compensation and 1.8V SMBus Communications PRODUCT FEATURES General Description The EMC1183 is a high accuracy, low cost, 1.8V System Management Bus (SMBus) compatible temperature sensor. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/transistor model including 65nm and lower geometry processors) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications. The ability to communicate at 1.8V SMBus levels provides compatible I/O for the advanced processors found in today’s tablet and smartphone applications. The EMC1183 monitors three temperature channels (two external and one internal), providing ±1°C accuracy for both external and internal diode temperatures. REC automatically eliminates the temperature error caused by series resistance allowing greater flexibility in routing thermal diodes. ...
