The QT240-ISSG from Microchip Technology is a self-contained digital sensor IC capable of detecting near-proximity or touch on four electrodes. It allows electrodes to project independent sense fields through any dielectric material like glass, plastic, stone, ceramic, and wood. This IC is designed for human interfaces such as control panels, appliances, gaming devices, and lighting controls.
Key features include four independent charge-transfer touch keys, individual active-high outputs per channel, and continuous self-calibration for long-term reliability. The device supports a voltage range of 3.9V to 5V and operates between -40°C and 85°C. It also incorporates spread-spectrum modulation for enhanced EMC compliance and a sync pin for noise suppression.
The QT240-ISSG is housed in a 20-SSOP package and is suitable for surface mount applications. Its design allows for easy sensitivity tuning on a per-channel basis, making it a versatile component for new product concepts.
