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.
DNA Solutions has various makes & types of TouchSensor IC's. We deal in retail and bulk quantity as well. Check our collection of various types of TouchSensor IC.

Operating voltage:2.4V~5.5V
Built-in regulator with external enable/disable option
_x0083_Operating 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
_x0083_Sensitivity can adjust by the capacitance(0~50pF) outside for each touch pad
_x0083_Provides Fast mode and Low Power mode selection by pad option(LPMB pin)
_x0083_Provides direct mode or toggle mode
CMOS output or open drain output
Active high or active low by pad option(TOG/OD/AHLB pin).
_x0083_Provides 2 output pins TPQ0D, TPQ2D that have no diode protection, active low
_x0083_Have the maximum on time 120sec/64sec/16sec/infinite by pad option(MOT1, MOT0 pin)
_x0083_After power-on have about 0.5sec stable-time, during the time do not touch the key pad, and the function is disabled
_x0083_Auto calibration for life, and the re-calibration period is about 4.0sec, when key has not be touched.
