Overview
The QT510-IS is a capacitive touch sensor integrated circuit designed for rotary wheel interfaces, manufactured by Microchip Technology. It operates within a supply voltage range of 2.5V to 5V and draws a supply current of 750µA. The device features a 7-bit resolution and supports an SPI interface for data communication. It includes three input channels and offers proximity detection capabilities. The component is housed in a 14-TSSOP package with a width of 4.40mm and functions reliably across an operating temperature range of -40°C to 85°C.
Feature Summary
- Capacitive sensing technology optimized for rotary wheel applications
- Integrated proximity detection functionality
- SPI digital interface for system connectivity
Applications
- Rotary encoder implementations
- User interface control wheels
- Proximity-based interaction systems
Procurement Notes
Verify the specific suffix IS against official Microchip documentation to confirm package type and temperature grade. Confirm end-of-life status as distributor listings indicate this part may be discontinued. Ensure compatibility with existing PCB footprints for the 14-TSSOP form factor before procurement.
Selection Notes
Select this component when a dedicated rotary wheel controller with proximity sensing is required. Verify that the 7-bit resolution meets the precision requirements of the application. Ensure the host microcontroller supports the SPI protocol used for communication. Check that the 2.5V to 5V supply range aligns with the system power architecture.
Part Context
This part belongs to the QSlide and QWheel series from Microchip Technology. It is distinct from general-purpose touch controllers by focusing specifically on rotary input mechanisms. The IS suffix typically denotes the industrial temperature grade and TSSOP packaging variant within the broader QT510 product family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Microchip engineering support for direct replacements or pin-compatible alternatives if this component is no longer in production.
