TTP223N-BA6 datasheet pdf


The TTP223N-BA6 TonTouch 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. Low power consumption and wide operating voltage are the contact key features for DC or AC application.

A Touch Pad Detector IC, often referred to as a touch controller or touch sensor IC, is an integrated circuit designed to detect and interpret touch or proximity input from a user. These ICs are commonly used in various electronic devices, including smartphones, tablets, laptops, touchpads, touchscreens, and other human-machine interface (HMI) applications.


1. Operating voltage 2.0V~5.5V

2. Operating current @VDD=3V, no load

3. At low power mode typical 1.5uA, maximum 3.0uA

4. The response time max 220mS at low power mode @VDD=3V

5.  Sensitivity can adjust by the capacitance(1~50pF) outside
