Overview
The Microchip Technology QT60160-ATG is a 16-key QMatrix touch sensor IC utilizing patented spread-spectrum charge-transfer technology. It operates on a 1.8V to 5.5V supply with low power consumption of 40µA in low-power mode. The device features an I2C serial interface and supports self-calibration, auto drift compensation, and noise filtering. Packaged in a 32-pin 5x5mm MLF, it functions within a temperature range of -40°C to +85°C.
Feature Summary
- Patented transverse charge-transfer sensing for stable operation under varying conditions
- Integrated signal processing including self-calibration and adjacent key suppression
- Spread-spectrum burst modulation to minimize EMI effects and RF emissions
Applications
- Mobile phones and remote controls
- Domestic appliances and PC peripherals
- Automotive interfaces
Procurement Notes
Verify the specific ATG ordering suffix against official Microchip documentation to confirm package and temperature grade details. Ensure compliance with moisture sensitivity levels during storage and handling. Confirm availability through authorized distributors as lead times may vary.
Selection Notes
Select this component for applications requiring robust capacitive touch sensing with minimal external components. The 16-key capacity suits compact control panels. Consider the I2C interface compatibility with the host microcontroller and ensure PCB layout adheres to strict grounding rules to prevent noise interference.
Part Context
This part belongs to the QT60xx0 family of digital burst mode charge-transfer sensors. It shares functional similarities with the QT60240 but is limited to 16 keys. Both variants utilize the same 32-pin MLF package and core sensing technology, differing primarily in the maximum number of supported keys.
Replacement Considerations
The QT60240-ISG is a compatible alternative offering up to 24 keys with identical pinout and functionality. Verify that the additional key capacity does not impact board space or software configuration requirements.
