This touch detection ic is designed for replacing traditional direct button key with diverse pad size.
The ttp223 capacitive touch sensor module contains a touch pad.
How to use a ttp223 touch switch 2.
The operating voltage of the ttp223 ic is from the 2v to 5 5v and the power consumption of the touch sensor is very low.
Four different modes of ttp223 touch switch 3.
When there is contact with the surface of the touch sensor the circuit inside the sensor becomes closed and there is a flow of current.
At the heart of the circuit is an inexpensive 20 smd chip ttp223 commonly available in ba 6 package.
