CAP1296-1-AIA-TR

Overview

The CAP1296-1-AIA-TR is a six-channel capacitive touch sensor controller manufactured by Microchip Technology. It features programmable sensitivity, automatic recalibration for parasitic capacitance, and proximity detection with an optional signal guard. The device supports SMBus/I2C communication, operates on a 3.0V to 5.5V supply, and includes multiple power states including Deep Sleep (5µA typical). It is housed in a 10-pin 3mm x 3mm DFN package.

Feature Summary

Six individual capacitive touch sensor inputs with programmable sensitivity and automatic recalibration
Proximity detection capability with signal guard output to reduce noise sensitivity
Multiple pattern touch recognition allowing simultaneous button detection
Low power operation with Deep Sleep state drawing 5µA typical current

Applications

Desktop and Notebook PCs
LCD Monitors
Consumer Electronics
Appliances

Procurement Notes

Verify the complete part number against official Microchip documentation to ensure correct suffixes for packaging and temperature range. Confirm interface compatibility with the host system's SMBus or I2C controller before integration.

Selection Notes

Select this component when a multi-channel touch solution with integrated proximity sensing is required. Ensure the host system supports SMBus or I2C protocols and can accommodate the 3.0V to 5.5V operating voltage range of the device.

Part Context

The CAP1296 belongs to Microchip's RightTouch capacitive touch controller family. It is designed to replace mechanical switches in user interfaces, offering a robust alternative with software-configurable parameters for sensitivity and response time.

Replacement Considerations

Check for direct pin-compatible alternatives within the CAP12XX series if channel count or package requirements differ. Verify register compatibility if migrating from older touch controller models.

FAQ

What is the function of the CS3/SG pin?

The CS3/SG pin serves as Capacitive Touch Sensor Input 3. When proximity detection is enabled, it also functions as the Signal Guard output to isolate the proximity antenna.
