EMC181x Multi-Channel Sensors

Microchip’s EMC181x low-voltage multi-channel diode sensors

Image of Microchip Technology's EMC181x Multi-Channel SensorsMicrochip’s EMC181x family of multi-channel temperature sensors provides up to four external temperature monitors. The device reports rate of change of temperature in addition to standard temperature, which provides an additional protective layer to manage varying system temperatures. These sensors are ideal for any low-cost, highly flexible, and accurate solution for critical temperature monitoring applications.

The EMC1812/13/14/15/33 devices are high-accuracy, 2-wire (I2C) temperature sensors. 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, IoT, temperature sensitive storage, industrial, and computing applications.
