MCP9902T-AE/RW IC Sensors by Microchip Technology
Cold Accurate Dual Temperature Sensor
| Status: | Active |
|---|---|
| Series: | MCP9902 |
| RoHS: | Compliant |
The MCP9902 is a high accuracy, low cost, System Management Bus (SMBus) temperature sensor (shared data sheet with MCP9903 & MCP9904). 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 MCP9902 monitors two temperature channels (one external and one internal). It provides ±1°C 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 the 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° measurement accuracy provide a low-cost, highly flexible and accurate solution for critical temperature monitoring applications.
