Part Number: AT42QT1010
Function: Single-key QTouch Touch Sensor IC
Package: SOT23-6 Type
Manufacturer: Microchip, Atmel Corporation
Image and Pinouts:
The AT42QT1010 (QT1010) is a digital burst mode charge-transfer (QT) sensor that is capable of detecting near proximity or touch, making it idealfor implementing touch controls.
With the proper electrode and circuit design, the self-containeddigital IC will project a touch or proximity field to several centimeters through any dielectric like glass, plastic, stone, ceramic, and even most kinds of wood.
It can also turn small metal-bearing objects into intrinsic sensors, making them responsive to proximity or touch. This capability, coupled with its ability to self-calibrate, can lead to entirely new product concepts.
