EMC1403/EMC1404 1C Temperature Sensor with Beta Compensation Data Sheet PRODUCT FEATURES General Description Applications Notebook Computers The EMC1403 and EMC1404 are high accuracy, low Desktop Computers cost, System Management Bus (SMBus) temperature Industrial sensors. Advanced features such as Resistance Error Embedded applications Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/transistor model including Features 45nm, 65nm and 90nm processors) and automatic Support for diodes requiring the BJT/transistor model diode type detection combine to provide a robust supports 45nm, 65nm, and 90nm CPU thermal diodes. solution for complex environmental monitoring Automatically determines external diode type and applications. optimal settings Resistance Error Correction Each device provides 1 accuracy for external diode External Temperature Monitors temperatures and 2C accuracy for the internal diode 1C Accuracy (60C < T < 100C) DIODE temperature. The EMC1403 monitors three temperature 0.125C Resolution channels (two external and one internal). The EMC1404 Anti-parallel diodes for extra diode support monitors four temperature channels (three external and Internal Temperature Monitor one internal). 2C accuracy 3.3V Supply Voltage Resistance Error Correction automatically eliminates the Programmable temperature limits for ALERT and temperature error caused by series resistance allowing THERM greater flexibility in routing thermal diodes. Beta Available in these RoHS Compliant Packages Compensation eliminates temperature errors caused by 10-pin 3mm x 3mm DFN low, variable beta transistors common in today s fine 10-pin MSOP geometry processors. The automatic beta detection 14-pin SOIC 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 1C measurement accuracy provide a low-cost, highly flexible and accurate solution for critical temperature monitoring applications. 2014 Microchip Technology Inc. 1DS20005272A-page 1C Temperature Sensor with Beta Compensation Data Sheet Ordering Information: EMC1403-1-AIZL-TR for 10-pin, MSOP RoHS Compliant Package EMC1403-2-AIZL-TR for 10-pin, MSOP RoHS Compliant Package EMC1403-3-AIZL-TR for 10-pin, MSOP RoHS Compliant Package EMC1403-4-AIZL-TR for 10-pin, MSOP RoHS Compliant Package EMC1403-1-AIA-TR for 10-pin, DFN RoHS Compliant Package EMC1403-2-AIA-TR for 10-pin, DFN RoHS Compliant Package EMC1403-3-AIA-TR for 10-pin, DFN RoHS Compliant Package EMC1403-4-AIA-TR for 10-pin, DFN RoHS Compliant Package EMC1403-1-YZT-TR for 14-pin, SOIC RoHS Compliant Package EMC1403-2-YZt-TR for 14-pin, SOIC RoHS Compliant Package EMC1403-3-YZt-TR for 14-pin, SOIC RoHS Compliant Package EMC1403-4-YZt-TR for 14-pin, SOIC RoHS Compliant Package EMC1404-1-AIZL-TR for 10-pin, MSOP RoHS Compliant Package EMC1404-2-AIZL-TR for 10-pin, MSOP RoHS Compliant Package EMC1404-3-AIZL-TR for 10-pin, MSOP RoHS Compliant Package EMC1404-4-AIZL-TR for 10-pin, MSOP RoHS Compliant Package Note: See T 1.1, ablePart Selectio for SMBus addressing options.
