TTP223B TOUCH MODULE Capacitive Touch Switch

TTP223B TOUCH MODULE Capacitive Touch Switch

Touch Sensor Interface :

1. Control Interface: A total of three pins (GND, VCC, SIG), GND to the ground, VCC is the power supply, SIG digital signal output pin
2. Power Indicator: Green LED, power on the right that is shiny
3. Touch area: Similar to a fingerprint icon inside the area, you can touch the trigger finger.
4. Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination.

Features :

1. Low power consumption
2. Power supply for 2 ~ 5.5V DC
3. Can replace the traditional touch of a button
4. Four M2 screws positioning holes for easy installation
5. Output Pin Sink Current (@ VCC = 3V, VOL = 0.6V) : 8 mA
6. Output pin pull-up current (@ VCC = 3V, VOH = 2.4V) : 4 mA

Input Voltage : 2 Volt – 5.5 Volts DC.
The response time max ~ 60mS in fast mode, ~220mS at low power mode @VDD=3V.
Sensitivity can adjust by the capacitance(0~50pF).
Stable touching detection of the human body for replacing traditional direct switch key.
Provides direct mode toggle mode by pad option(TOG pin).
After power-on have about 0.5sec stable-time, during the time do not touch the keypad, and the function is disabled.
Auto calibration and Re-calibration period is about 4.0 sec when the key has not be touched.
