TTP224
capacitive sensing design specifically for touch pad controls.
Features:
Package: SSOP16
Operating voltage: 2.4V~5.5V
Built-in regulator with external enable/disable option
Operating current, @VDD=3V no load
At low power mode typical 2.5uA
At fast mode typical 9.0uA
@VDD=3V operating voltage :Sensitivity can adjust by the capacitance(0~50pF) outside for each touch pad
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
Provides Fast mode and Low Power mode selection by pad option(LPMB pin)
Provides direct mode or toggle mode、CMOS output or open drain output active high or active low by pad option(TOG/OD/AHLB pin).
Provides 2 output pins TPQ0D, TPQ2D that have no diode protection, active low
Have the maximum on time 120sec/64sec/16sec/i
nfinite by pad option(MOT1, MOT0 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.
