TTP224 Touch Sensor IC

The TTP224/TTP224N TonTouch TM IC is capacitive sensing design specifically for touch pad  controls. The device built in regulator for touch sensor. Stable sensing method can cover diversity conditions. Human interfaces control panel links  through non-conductive dielectric material. The main application is focused at replacing of the mechanical switch or button. The ASSP can independently handle the 4 touch pads with 4 direct output pins.


Features of TTP224 Touch IC

  • Operating voltage:2.4V~5.5V

  • Built-in regulator with external enable/disable option

  • ƒOperating current, @VDD=3V no load

  • At low power mode typical 2.5uA

  • At fast mode typical 9.0uA 

  • @VDD=3V operating  voltage  :     

  • The response time about 100mS at fast mode, 200mS at low power mode for TTP224

  • The response time about 60mS at fast mode, 160mS at low power mode for TTP224N

  • ƒSensitivity can adjust by the capacitance(0~50pF) outside for each touch pad

  • ƒProvides Fast mode and Low Power mode selection by pad option(LPMB pin)

  • ƒProvides direct mode or toggle mode

  • CMOS output or open drain output

  • Active high or active low by pad option(TOG/OD/AHLB pin).

  • ƒProvides 2 output pins TPQ0D, TPQ2D that have no diode protection, active low

  • ƒHave the maximum on time 120sec/64sec/16sec/infinite by pad option(MOT1, MOT0 pin)

  • ƒAfter power-on have about 0.5sec stable-time, during the time do not touch the key pad, and the function is disabled

  • ƒAuto calibration for life, and the re-calibration period is about 4.0sec, when key has not be touched.
