TTP223 Touch Key Module

Specification :

• 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.

Trigger-setting mode: (1- > Short ; 0- > No Short)
