The TTP229 is capacitive sensing design specifically for touch pad controls. The device has a built in regulator for the touch sensor. Stable sensing method can cover diversity conditions. Interface control panel links through non-conductive dielectric material. The main application is focused at replacing of the mechanical switch or button. This board can independently handle the 8 touch pads with 8 direct output pins.
