The EMC1413 is a three-channel SMBus temperature sensor with ±1°C accuracy for both external and internal diode measurements, offering 0.125°C resolution. It features Resistance Error Correction for up to 100 Ω of series resistance and Beta Compensation to support CPU diodes and discrete transistors with variable beta. The device includes an internal temperature monitor and supports programmable temperature limits and ALERT output modes. It operates from a 3.3V supply and is available in a 10-pin 3mm x 3mm DFN package or a 10-pin MSOP package. It is RoHS compliant and supports programmable SMBus address selection via a THERM pin pull-up resistor.
The EMC1413/EMC1414 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.
The EMC1413 monitors three temperature channels and the EMC1414 monitors four temperature channels. It provides ±1ºC 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 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.
