Super Debug TTP223 Capacitive Switch Button Module Self-Lock High Low Level OutputTTP223 Capacitive Switch Button Module Self-Lock High Low Level OutputThe TTP223 Touch Key Module is based on a touch-sensing IC (TTP223) capacitive touch switch module. A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm.An onboard LED will give a visual indication of when the sensor is triggered.Trigger-setting mode: (1- > Short ; 0- > No Short)AB=00: No-lock High TTL level output; AB=01: Self-lock High TTL level output; AB=10: No-lock Low TTL level output; AB=11: Self-lock Low TTL level output;TTP223 Capacitive Switch Button ModuleInput Voltage : 2 Volt – 5.5 Volts DCThe response time max ~ 60mS in fast mode, ~220mS at low power mode @VDD=3VSensitivity can adjust by the capacitance(0~50pF)Stable touching detection of the human body for replacing traditional direct switch keyProvides direct mode toggle mode by pad option(TOG pin)After power-on have about 0.5sec stableTime,during time dont touch the keypad, function is disabledAuto calibration and Re-calibration period is about 4.0 sec when the key has not be touchedOther FeaturesProvides direct mode?toggle mode by pad option(TOG pin).In the open-drain mode by bonding option, OPDO pin is an open-drain output, Q pin is CMOS output.All output modes can be selected as 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.Connection Mode :TTP223When triggered the output of the module will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output.TTP223 Capacitive Touch Sensor Module. The TTP223 is a touchpad detector IC replicating a single tactile button.The TTP223 is a touchpad detector IC replicating a single tactile button. This touch detection IC is designed for replacing traditional direct button keys with diverse pad sizes.Key Features of TTP223Supports momentary or latching/toggle modes.Supports Active High or Active Low output signal modes.Dimensions : 15mm x 11mm.Input Voltage: 2 Volt – 5.5 Volts DC.The response time max is ~ 60mS in fast mode, ~220mS at low power mode @VDD=3V.Sensitivity can adjust by the capacitance(0~50pF).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).
