The TTP226 is a touchpad detector IC which offers 8 touch key. The touching detection IC is designed for replacing the traditional direct button key with a diverse pad size. Capacitive touch allows electronics to sense when your finger is within a few millimeters of a surface to simulate a button “press” just like how the pushbutton works. Capacitive sensing may be used in any place where low to no force human touch sensing is desirable. 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.
