Q: What is TTP223?

The TTP223 is a single-touch pad detector IC with a single touch key. The touching detection IC is intended to be used in place of typical direct button keys with a variety of pad sizes. The contact essential benefits for DC or AC applications are low power consumption and a wide operating voltage range.

Q: How does a TTP223 work?

The TTP223 is an IC that simulates a single tactile button on a touch pad. This touch detecting IC is intended to be used in place of typical direct button keys with a variety of pad sizes. 3. Human body contact detection that is stable enough to replace the typical direct switch key.

Q: How do I increase the sensitivity of my TTP223?

Outside, the TTP223 has a few options for changing the sensitivity. 1-1 multiplied by the electrode size Other circumstances are set. Sensitivity can be improved by using larger electrodes. Otherwise, sensitivity may be reduced.

Overview of TTP223

The TonTouchTM TTP223 is a touchpad detector IC with a one-touch key. The touching detection IC is intended to be used in place of typical direct button keys with a variety of pad sizes. The contact essential benefits for DC or AC applications are low power consumption and a wide operating voltage range.

TTP223 Features

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 the human body for replacing the 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 keypad, And the function is disabled
Auto 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-BA6 is worse than TTP223-BA6’s.
