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 millimeters of the surface to simulate a button “press” just like how the push button works.

Features:

• On-board TTP224 capacitive touch 4 key IC
• On-board 4 road level indicator.
• Working voltage: 2 V to 5.5 V DC
• Adjustable output mode, key output mode, longest time and fast/low power output
• PCB board size: 35(mm) x29 (mm).

Applications of TTP224 4 Channel Digital Touch Sensor:

• It is used in touch switch in consumer and industrial purposes.
