Microchip Technology Temperature Sensor Evaluation Board

Microchip Technology’s EMC1833 Temperature Sensor Evaluation Board demonstrates the performance and features of the EMC1833 3-channel temperature sensor.

The board includes an anti-parallel connected transistor, a header for connecting to an external diode, CPU, or GPU, and multiple test points. The board also includes a USB-to-SMBus bridge for power and communications with the host PC and is supported by Microchip’s Thermal Management Utility, used to plot temperature measurements, set alert temperatures, and modify registers.

The EMC1833 features temperature rate of change calculation with preemptive alert limits to improve monitoring and management of variable system temperatures. The sensor is accurate to ±1°C, has 0.125°C resolution, and includes automatic beta compensation and resistance error correction for maximum accuracy in the final design.

The EMC1833 can operate from a 1.62V to 3.6V supply, providing a seamless migration path to lower operating voltages.
