Microchip Technology EMC181x Remote Diode Sensors
Microchip EMC181x Remote Diode Sensors offer multiple channels and low-voltage in high-accuracy, 2-wire (I2C) temperature sensors. Five temperature channels can be monitored. The EMC181x Sensors measure the temperature rate of change calculation, including preemptive alert limits. This provides another protective measurement layer to watch and manage variable system temperatures.
Complex environmental monitoring applications benefit from advanced features such as Resistance Error Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/Transistor model), and rate of temperature change measurement.
Greater flexibility is allowed in routing thermal diodes created by the Resistance Error Correction feature. This feature automatically eliminates the temperature error caused by series resistance. The Beta compensation feature eliminates temperature errors caused by low, variable beta transistors, resulting in automatic beta detection.
Offering these advanced features combined with ±1°C measurement accuracy for both external and internal diode temperatures makes the EMC181x ideal for a low-cost, highly flexible, and accurate solution for critical temperature monitoring applications.
