1 KEY TOUCH PAD DETECTOR IC
GENERAL DESCRIPTION
The TTP223N-HA6 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(1~50pF) 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) Have the maximum on time 100sec After power-on have about 0.5sec stable-time, during the time do not touch the key pad,...
