1 KEY TOUCH PAD DETECTOR IC

GENERAL DESCRIPTION

The TTP223-BA6/TTP223N-BA6 TonTouch^TMis 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
