Consumer electronics
Appliances

Procurement Notes

Verify the specific ordering suffix '-BP' against official Microchip documentation to confirm the exact package type and tape & reel specifications. Ensure that the selected communication protocol configuration matches the required host controller interface before finalizing procurement orders.

Selection Notes

Select this component for applications requiring eight independent touch channels and integrated LED control. Verify that the system power supply remains within the 3V to 3.6V range. Confirm that the available PCB space accommodates the 20-pin QFN package dimensions and thermal requirements.

Part Context

This part belongs to the CAP11xx series of capacitive touch sensors from Microchip Technology. It utilizes RightTouch technology for reliable sensing performance. The device integrates both sensing and output driving capabilities into a single low-power solution suitable for compact electronic designs.

Replacement Considerations

Consult official Microchip documentation for confirmed substitute part numbers. Do not assume functional equivalence with other models without verifying pinout compatibility and electrical specifications.
