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
ƒ Operating voltage 2.0V~5.5V
ƒ Operating current @VDD=3V, no load
ƒ At low power mode typical 1.5uA, maximum 3.0uA
ƒ The response time max 220mS at low power mode @VDD=3V
ƒ Sensitivity can adjust by the capacitance(0~50pF) outside
ƒ Stable touching detection of human body for replacing traditional direct switch key
ƒ Provides Low Power mode
ƒ Provides direct modetoggle mode by pad option(TOG pin)
Q pin is CMOS output
ƒ All output modes can be selected active high or active low by pad option(AHLB pin)
ƒ After power-on have about 0.5sec stable-time, during the time do not touch the key pad,
And the function is disabled
ƒ 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
ƒ The sensitivity of TTP223N-BA6 is better than TTP223-BA6’s.
But the stability of TTP223N-BA6 is worse than TTP223-BA6’s.
APPLICATION
ƒ Wide consumer products
ƒ Button key replacement
