TonTouchTM
1 KEY TOUCH PAD DETECTOR IC
GENERAL DESCRIPTION
The TTP223-BA6/TTP223N-BA6 TonTouchTM is a touch pad detector IC which offers 1 touch
key. The touching detection 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.
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 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
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.
APPLICATION
Wide consumer products
Button key replacement

FUNCTION DESCRIPTION
1. Sensitivity adjustment
The total loading of electrode size and capacitance of connecting line on PCB can affect the
sensitivity. So the sensitivity adjustment must according to the practical application on PCB. The
TTP223-BA6/TTP223N-BA6 offers some methods for adjusting the sensitivity outside.
1-1 by the electrode size
Under other conditions are fixed. Using a larger electrode size can increase sensitivity. Otherwise it
can decrease sensitivity. But the electrode size must use in the effective scope.
1-2 by the panel thickness
Under other conditions are fixed. Using a thinner panel can increase sensitivity. Otherwise it can
decrease sensitivity. But the panel thickness must be below the maximum value.
1-3 by the value of Cs (please see the down figure)
Under other conditions are fixed. When do not use the Cs to VSS, the sensitivity is most sensitive.
When adding the values of Cs will reduce sensitivity in the useful range (0≦Cs≦50pF).

2. Output mode
The TTP223-BA6/TTP223N-BA6 has direct mode active high or low by AHLB pad option. And
has toggle mode by TOG pad option. Pad Q is CMOS output.
