Electronic Switches/Keypads Modules
TTP223 Touch Key Module – 2Pcs
- 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.
