Description

The TTP224 is a touch pad detector IC which offers 4 touch key. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Capacitive touch allows electronics to sense when your finger is within a few millimetres 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.
