MTCH1030-E/ST

Overview

The MTCH1030-E/ST is a capacitive touch controller providing up to three sensors with Driven Shield+ capability. It operates on a supply voltage of 2V to 5V and supports an industrial temperature range of -40°C to +85°C. The device features configurable measurement periods, oversampling levels, and sensitivity via dedicated pins. It includes Easy Tune for automatic sensitivity adjustment and Single-Button mode for power optimization.

Feature Summary

• Capacitive touch sensing with Driven Shield+ technology
• Automatic environmental compensation and noise suppression
• Water-tolerant detection through various front panels
• Configurable sensitivity and measurement period

Applications

• Consumer electronics touch interfaces
• Industrial control panels requiring water tolerance
• Appliances with metal or plastic overlays

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +85°C) compared to standard variants. Confirm the '/ST' package designation matches the required 14-pin TSSOP footprint. Ensure the ordering code aligns with Microchip's current product identification system before finalizing procurement.

Selection Notes

Select this model when three independent sensor channels are required. Use the /ST package for surface-mount applications needing a 14-pin TSSOP form factor. Consider the -E suffix if operation in colder environments below commercial limits is necessary. Evaluate the need for GPIO configuration versus I2C interfaces available in other series members.

Part Context

This component belongs to the MTCH10xx series of capacitive touch controllers from Microchip Technology. It shares core tuning algorithms and interface structures with siblings like the MTCH1010 and MTCH1060. The primary distinction lies in the channel count and specific package availability within the broader family.

Replacement Considerations

Direct replacements include other MTCH1030 variants with different suffixes for package or temperature changes. Cross-series substitution requires verifying channel count compatibility and interface differences.
