1. Input Voltage: 3.3V – 5.5V DC TTP223 Capacitive Touch Sensor

2. Module size: 15mm x 11mm

3. Stable touching detection of human body for replacing traditional direct switch key.

For this tutorial, we required these items:

1. TTP223 Touch Sensor Module ( Capacitor)

2. 10mm LED (Yellow)

3. Resistor 220 ohm

4. Breadboard Power Stick 3.3V / 5V

5. Li-Ion Rechargable Battery 7.4V 1200mAh

Trigger setting mode: (1 = Short ; 0 = No Short)

Momentary / High Output 00 (used in this tutorial)

Self Lock / High Output 01

Momentary / Low Output 10

Self Lock / Low Output 11

Based on the results,

1. The LED will turn on when we touch the .

2. If no touching detected, the LED will turn off.

 Operating voltage 2.0V~5.5V



Operating current @VDD=3V, no load



low power mode typical 1.5uA, maximum 3.0uA



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



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)



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 is better than TTP223-BA6’s.



But the stability of MOEDULE is woe than TTP223-BA6’s.
