TTP233-JA6
TonTouchTM
1 KEY TOUCH PAD DETECTOR IC
GENERAL DESCRIPTION
The TTP233-JA6 TonTouchTM is a touch pad detector IC which offers 1 touch key. The device
built-in regulator for touch sensor. Stable sensing method can cover diversity condition. 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 2.1V~5.5V
ƒ Built-in regulator for touch sensor
ƒ TTP233-JA6 Operating current @VDD=3V, no load
At low power mode typical 2.5uA, maximum 5uA
At fast mode typical 5uA, maximum 10uA
ƒ The response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V
ƒ Sensitivity can adjust by the capacitance(1~50pF) outside
ƒ Stable touching detection of human body for replacing traditional direct switch key
ƒ Provides Fast mode and Low Power mode selection by pad option(LPMB pin)
ƒ Q pin is CMOS direct output, active high.
ƒ Have the maximum on time 80 sec
ƒ After power-on have about 0.5 sec stable-time, during the time do not touch the key pad,
And the function is disabled
ƒ Auto calibration for life
The re-calibration period is about 1 sec within 8 sec after power-on. When key has be
touched within 8 sec or key has not be touched more than 8 sec after power-on, then the
re-calibration period change to 4 sec.
APPLICATION
ƒ Wide consumer products
ƒ Button key replacement
