TTP223B Digital Touch Sensor
SummaryThe TTP223 is a touch pad detector IC which offers 1 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.
On-board TTP223 capacitive touch a single bond induction IC;
Board level indicator;
Working voltage: 2.0 V to 5.5 V;
Size of the PCB board: 29mm x 16mm.
