Description: The TTP223 is a touch pad detector IC which offers 1 touch key. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Low power consumption and wide operating voltage are the contact key features for DC or AC application.



Features:
  • Package: SOT-23-6L
  • Operating voltage 2.0V~5.5V
  • Operating current @VDD=3V, no load, SLRFTB=1
    • At low power mode typical 1.5uA, maximum 3.0uA
    • At fast mode typical 3.5uA, maximum 7.0uA
  • Operating current  @VDD=3V, no load, SLRFTB=0
    • At low power mode typical 2.0uA, maximum 4.0uA
    • At fast mode typical 6.5uA, maximum 13.0uA
  • The response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V
  • Sensitivity can adjust by the capacitance(0~50pF) outside
  • 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 modeselection by pad option(LPMB pin)
  • Provides direct mode、toggle mode by pad option(TOG pin)
  • All output modes can be selected active
  • high or active low by pad option(AHLB pin)
  • Have the maximum on time 100sec 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
  • Auto calibration for life And the re-calibration period is about 4.0sec, when key has not be touched
Application:
  • Wide consumer products
  • Water proofed electric products
  • Button key replacement
