The devices monitor up to five temperature channels. 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 combine to provide a robust solution for complex environmental monitoring applications. Datasheet DS20005751A-page 1 2018 Microchip Technology Inc. Multi-Channel Low-Voltage Remote Diode Sensor Family This device family introduces rate of change temperature measurement with associated alerts. This provides a preemptive system alert and another protective measurement layer to catch and manage variable system temperatures. The Resistance Error Correction feature automatically eliminates the temperature error caused by series resistance, allowing for greater flexibility in routing thermal diodes. Beta compensation eliminates temperature errors caused by low, variable beta transistors common in current fine geometry processors. The automatic beta detection feature determines the optimal sensor external diode/transistor settings. This frees up the user from providing unique sensor configurations for each temperature monitoring application. These advanced features plus 1C measurement accuracy for both external and internal diode temperatures provide a low-cost, highly flexible and accurate solution for critical temperature monitoring applications.
