Introduction

AI Translation

The AT42QT1012 (QT1012) is a single key device featuring a touch on/touch off (toggle) output with a programmable auto switch- off capability. The device is One- channel Toggle- mode QTouch® Touch Sensor IC with Power Management Functions. The QT1012 features a digital burst mode charge- transfer sensor designed specifically for touch controls and a unique "green" feature - the timeout function, which can turn off power after a time delay.
