The AT42QT1060 touch control chip integrates 6-channels of touch sensing with the ability to drive up to 7 low current LEDs directly through a PWM output function. The device operates from 5.5 Vdc down to 1.8 Vdc and consumes less than 1 μA in standby mode.
Features include a built-in capacitive guard channel that helps prevent false triggering, for example, where moisture is an issue. The sensor chip is based on the company’s QTouch charge-transfer sensing method. Housed in a MLF28 package, the part also offers a host wake up function and GPIO expansion.
