DS20005272A-page 1 Data Sheet PRODUCT FEATURES EMC1403/EMC1404 1°C Temperature Sensor with Beta Compensation General Description The EMC1403 and EMC1404 are high accuracy, low cost, System Management Bus (SMBus) temperature sensors. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/transistor model including 45nm, 65nm and 90nm processors) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications. Each device provides ±1° accuracy for external diode temperatures and ±2°C accuracy for the internal diode temperature. The EMC1403 monitors three temperature channels (two external and one internal). The EMC1404 monitors four temperature channels (three external and one internal). Resistance Error Correction automatically eliminates the temperature error caused by series resistance allowing greater flexibility in routing thermal diodes. Beta Compensation eliminates temperature errors caused by low, variable beta transistors common in today's fine geometry processors. The automatic beta detection feature monitors each external diode/transistor and determines the optimum sensor settings for accurate temperature measurements regardless of processor technology. This frees the user from providing unique sensor configurations for each temperature monitoring application. These advanced features plus ±1°C measurement accuracy provide a low-cost, highly flexible and accurate solution for critical temperature monitoring applications. Applications Notebook Computers Desktop Computers Industrial Embedded applications Features Support for diodes requiring the BJT/transistor model — supports 45nm, 65nm, and 90nm CPU thermal diodes.
