2 keys Touch Pad Detector IC TTP232 Outline z The TTP232 TonTouchTM IC is capacitive sensing design specifically for touch pad controls.

The device built in regulator for touch sensor.

Stable sensing method can cover diversity conditions.

Human interfaces control panel links through non-conductive dielectric material.

The main application is focused at replacing of the mechanical switch or button.

The ASSP can independently handle the 2 touch pads with 2 direct output pins Characteristic z Ope
