TTP223 Capacitive Touch Sensor is a touchpad detector IC replicating a single tactile button. The TTP223 is a touchpad detector IC replicating a single tactile button. This touch detection IC is designed for replacing traditional direct button key with diverse pad size.

When do not use the Cs to VSS, the sensitivity is most sensitive. When adding the values of Cs will reduce sensitivity in the useful range (0≦Cs≦50pF). The TTP223 has direct mode active high or low by AHLB pad option. And has toggle mode by TOG pad option.

This TTP223 Capacitive Touch Sensor module is based on a touch detection IC (TTP223) of Capacitive type touch jog switch module . This module default output low, the low-power mode to mode; when a finger touching the corresponding position, the module will output high and returns low again touch. Mode is switched to fast mode; when for 12 seconds without touching, the mode and switch to low-power mode.

The TTP223 Capacitive Touch Sensor module can be installed such as plastic, glass surface non-metallic materials, in addition to the thin piece of paper (non-metallic) covering the surface of the module, as long as the touch of the correct position, you can make hidden in the wall, desk and other places button.

An onboard LED will give a visual indication of when the sensor is triggered. When triggered the output of the module will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output.

Features: –

  • Operating voltage 2.0V~5.5V
  • Operating current @VDD=3V, no load
  • At low power mode typical 1.5uA, maximum 3.0uA
  • The response time max 220mS at low power mode @VDD=3V
  • Sensitivity can adjust by the capacitance(0~50pF) outside
  • Stable touching detection of human body for replacing traditional direct switch key
  • Provides Low Power mode
  • Provides direct mode, toggle mode by pad option(TOG pin) Q pin is CMOS output 
  • All output modes can be selected active high or active low by pad option(AHLB pin) ƒ After power-on have about 0.5sec stable-time, during the time do not touch the key pad, And the function is disabled
  • Auto calibration for life At low power mode the re-calibration period is about 4.0sec normally, When key detected touch and released touch, the auto re-calibration will be redoing after about 16sec from releasing key
  • The sensitivity of TTP223N-BA6 is better than TTP223-BA6’s. But the stability of TTP223N-BA6 is worse than TTP223-BA6’s.

TTP223 Capacitive Touch Sensor Specifications: –

  • Working Voltage Range: 2V to 5.5V
  • Output high VOH: 0.8VCC
  • Output low VOL: 0.3VCC
  • PCB Size: 24mm x 24mm
