TTP223 Touch Sensor IC Single Channel Capacitive Touch Detection Chip-SOT23-6 Package
TTP223 Touch Sensor IC Single Channel Capacitive Touch Detection Chip-SOT23-6 Package TTP223 Touch Sensor IC Single Channel Capacitive Touch Detection Chip-SOT23-6 Package The TTP223 is a touchpad detector IC that offers 1 touch key. Featured by Sharvi Electronics The touching detection IC is designed for replacing the traditional direct button key with diverse pad sizes. Low power consumption and wide operating voltage are the contact key features for DC or AC applications.
Features/Specs:
- 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 @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 the human body for replacing traditional direct switch key
- Provides Fast mode and Low Power mode selection by pad option(LPMB pin)
- Provides direct mode、toggle mode by pad option(TOG pin) Open-drain mode by bonding option, OPDO pin is an open-drain output, Q pin is CMOS output
- 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 keypad, And the function is disabled
- Auto calibration for life And the re-calibration period is about 4.0sec when the key has not to be touched
