Product 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.
