MCP9601-E/MX

Sensor And Detector Interfaces Overview

The MCP9601-E/MX is a thermocouple electromotive force to degree Celsius converter manufactured by Microchip Technology. It features integrated cold-junction compensation and supports Type K, J, T, N, S, E, B, and R thermocouples. The device provides a hot-junction accuracy of ±1.5°C maximum and ±0.5°C typical at VDD = 3.3V. Measurement resolution is +0.0625°C for both hot and cold junctions. It operates on a 2.7V to 5.5V supply with a typical operating current of 300 µA. The component utilizes an I²C interface and is housed in a 20-lead MQFN package.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official documentation to confirm the extended temperature range rating. Ensure the MQFN-20 package type matches the target PCB footprint requirements. Cross-reference the datasheet revision number to validate the electrical specifications before finalizing procurement orders.

Sensor And Detector Interfaces Selection Notes

Select this model when thermocouple wire integrity monitoring is required via open-circuit and short-circuit alerts. Compare against the MCP9600-E/MX if diagnostic features are unnecessary, or the MCP96L01-E/MX if lower accuracy specifications are acceptable for the application environment.

Sensor And Detector Interfaces Part Context

This component belongs to the MCP960X/L0X/RL0X family of thermocouple-to-digital converters. It shares the same physical package and core architecture as the MCP9600 and MCP96L00 series, differentiated primarily by its enhanced diagnostic detection features and specific accuracy class within the product line.

Sensor And Detector Interfaces FAQ

How does the MCP9601 detect thermocouple faults?

It uses a dedicated VSENSE pin to monitor the thermocouple circuit. An alert signal is asserted if the wire is broken (open-circuit) or shorted to ground or power.

What is the typical operating current consumption?

The typical operating current is 300 µA when the I²C interface is active.

Can the alert outputs be configured for different logic polarities?

Yes, the alert outputs can be configured as either active-low or active-high push-pull outputs.
