TTP223 Capacitive Touch Sensor Module

• Dimensions: 15mm x 11mm
• Input Voltage: 2V-5.5V DC
• The response time max ~ 60mS in fast mode, ~220mS at low power mode @VDD=3V
• Sensitivity can adjust by the capacitance (0~50pF)
• Have two kinds of sampling length by pad option (SLRFTB pin)
• Stable touching detection of human body for replacing traditional direct switch key
• Provides Fast mode and Low Power mode selection by pad option (LPMB pin)
• Provides direct mode toggle mode by pad option (TOG pin)
• Open drain mode by bonding option, OPDO pin is open drain output, Q pin is CMOS output
• All output modes can be selected active high or active low by pad option (AHLB pin)
• Have the maximum on time 100 sec by pad option (MOTB pin)
• Have external power on reset pin (RST pin)
• After power-on have about 0.5sec stable-time, during the time do not touch the key pad, and the function is disabled
