MCP9601T-E/MX

Sensor And Detector Interfaces Overview

The MCP9601T-E/MX is a board-mount temperature sensor IC that converts thermocouple electromotive force to degrees Celsius. It features integrated cold-junction compensation and supports Type K, J, T, N, S, E, B, and R thermocouples. The device provides hot-junction accuracy of ±0.5°C typical and ±1.5°C maximum. It includes programmable digital filters, four alert outputs, and open-circuit/short-circuit detection via the VSENSE pin. Operating on a 2.7V to 5.5V supply with a 300µA typical current, it communicates via a 100 kHz I²C interface. The component is housed in a 20-lead MQFN package.

Sensor And Detector Interfaces Feature Summary

• Integrated thermocouple open-circuit and short-circuit detection capabilities
• Four individually programmable temperature alert outputs for monitoring rising or falling temperatures
• User-selectable low-power modes including shutdown and burst sampling
• NIST ITS-90 based conversion coefficients for eight standard thermocouple types

Sensor And Detector Interfaces Applications

• Petrochemical thermal management systems
• Hand-held measurement equipment
• Industrial equipment thermal management
• Commercial and industrial ovens
• Industrial engine thermal monitors

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm the '-E' designation aligns with the specified industrial temperature range requirements. Ensure the MQFN-20 package dimensions match the target PCB footprint constraints during procurement planning.

Sensor And Detector Interfaces Selection Notes

Select this model over the MCP9600 variant if integrated thermocouple fault detection is required. Consider the MCP96L00 series only if lower accuracy specifications are acceptable for the application. Verify that the I²C bus address configuration using the ADDR pin allows for sufficient device density on the target system bus.

Sensor And Detector Interfaces Part Context

This component belongs to the MCP960X/L0X/RL0X family of thermocouple signal conditioning ICs. It shares the same core architecture as the MCP9600 but adds diagnostic features for wire integrity. The family utilizes a delta-sigma ADC core for high-resolution temperature conversion across various industrial thermocouple standards.

Sensor And Detector Interfaces FAQ

How does the MCP9601 detect thermocouple faults?

It uses the VSENSE pin to monitor voltage levels, asserting an alert signal when the thermocouple is shorted to ground/power or disconnected.

What is the maximum number of devices supported per I²C bus?

The device supports up to eight devices per I²C bus by utilizing the ADDR pin to set unique slave addresses.

Can the alert outputs be configured for different polarities?

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