TTP223 Touch Sensor IC

The TTP223-BA6/TTP223N-BA6 TonTouch is a touch sensor IC which offers 1 touch  key.

This touch Sensor IC is designed for replacing traditional direct button key with diverse pad size. Low power consumption and wide operating voltage are the contact key features for DC or AC application.

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.

Features of TTP223 Touch Sensor IC

• Operating voltage 2.0V~5.5V

• Operating current @VDD=3V, no load At low power mode typical 1.5uA,  maximum  3.0uA

• The response time max 220mS at low power mode @VDD=3V

• Sensitivity can adjust by the capacitance(0~50pF) outside

• Stable touching detection of human body for replacing traditional direct switch key

• Provides Low Power mode

• Provides direct mode

• toggle mode by pad option(TOG pin) Q pin is CMOS output 

• All output modes can be selected active high or active low by pad option(AHLB pin)

• After power-on have about 0.5sec stable-time, during the time do not touch the key pad, And the function is disabled

• ƒAuto calibration for life

• At low power mode the re-calibration period is about 4.0sec normally, When key detected touch and released touch, the auto re-calibration will be redoing after about 16sec from releasing key

• The sensitivity of TTP223N-BA6 is better than TTP223-BA6’s. But  the  stability  of TTP223N-B A6 is worse than TTP223-BA6’s.

Applications of TTP223 Touch IC

• Wide consumer products

• Button key replacement
