IC TOUCH TTP224

Operating voltage 2.4V~5.5Vƒ
Built-in regulator with external enable/disable option ƒ
Operating current, @VDD=3V no load 
At low power mode typical 2.5uA 
At fast mode typical 9.0uA ƒ
@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 ƒ Sensitivity can adjust by the capacitance(0~50pF) outside for each touch pad ƒ

Provides Fast mode and Low Power mode selection by pad option(LPMB pin) ƒ
Provides direct mode or toggle mode、
CMOS output or open drain output、active high or active low by pad option(TOG/OD/AHLB pin). ƒ Provides 2 output pins TPQ0D, TPQ2D that have no diode protection, active low ƒ
Have the maximum on time 120sec/64sec/16sec/infinite by pad option(MOT1, MOT0 pin) ƒ
After power-on have about 0.5sec stable-time, during the time do not touch the key pad, and the function is disabled ƒ
Auto calibration for life, and the re-calibration period is about 4.0sec, when key has not be touched.
