EMC1413/EMC1414 Multiple Channel 1C Temperature Sensors with Beta Compensation Data Sheet PRODUCT FEATURES General Description Applications Notebook Computers The EMC1413/EMC1414 are high accuracy, low cost, Desktop Computers 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) and Features automatic diode type detection combine to provide a Programmable SMBus address robust solution for complex environmental monitoring Support for diodes requiring the BJT/transistor model applications. including advanced processor geometries Automatically determines external diode type and The EMC1413 monitors three temperature channels and optimal settings the EMC1414 monitors four temperature channels. It Resistance Error Correction provides 1C accuracy for both external and internal Up to 3 External Temperature Monitors diode temperatures. 1C max accuracy (20C < T < 110C) DIODE 0.125C resolution Resistance Error Correction automatically eliminates the Supports up to 2.2nF diode filter capacitor temperature error caused by series resistance allowing Anti-parallel diodes for extra diode support (EMC1414 greater flexibility in routing thermal diodes. Beta only) Compensation eliminates temperature errors caused by Internal Temperature Monitor low, variable beta transistors common in today s fine 1C accuracy geometry processors. The automatic beta detection 0.125C resolution feature monitors each external diode/transistor and 3.3V Supply Voltage determines the optimum sensor settings for accurate Programmable temperature limits for ALERT temperature measurements regardless of processor Available in these RoHS compliant packages technology. This frees the user from providing unique 10-pin 3mm x 3mm DFN sensor configurations for each temperature monitoring 10-pin MSOP 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. 1DS20005274A-page Multiple Channel 1C Temperature Sensors with Beta Compensation Data Sheet Ordering Information: SMBUS ORDERING NUMBER PACKAGE FEATURES ADDRESS EMC1413-1-AIZL-TR 10-pin MSOP Up to three temperature sensors, ALERT and 1001 100(r/w) (RoHS compliant) THERM pins, fixed SMBus address EMC1413-A-AIZL-TR 10-pin MSOP Up to three temperature sensors, ALERT and Selectable via (RoHS compliant) THERM pins, programmable SMBus address THERM pull-up EMC1413-A-AIA-TR 10-pin DFN 3mm x 3mm Up to three temperature sensors, ALERT and Selectable via (RoHS compliant) THERM pins, programmable SMBus address THERM pull-up EMC1413-3-AIZL-TR 10-pin MSOP Up to three temperature sensors, ALERT and 0011 000(r/w) (RoHS compliant) THERM pins, programmable SMBus address EMC1414-1-AIZL-TR 10-pin MSOP Up to four temperature sensors, ALERT and 1001 100(r/w) (RoHS compliant) THERM pins, fixed SMBus address EMC1414-A-AIZL-TR 10-pin MSOP Up to four temperature sensors, ALERT and Selectable via (RoHS compliant) THERM pins, programmable SMBus address THERM pull-up EMC1414-A-AIA-TR 10-pin DFN 3mm x 3mm Up to four temperature sensors, ALERT and Selectable via (RoHS compliant) THERM pins, programmable SMBus address THERM pull-up REEL SIZE IS 4,000 PIECES This product meets the halogen maximum concentration values per IEC61249-2-21 TO OUR VALUED CUSTOMERS It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip products.
