Preliminary TTP224N-FO8 TonTouchTM 1 KEY TOUCH PAD DETECTOR IC GENERAL DESCRIPTION The TTP224N-FO8 TonTouchTM IC is capacitive sensing design specifically for touch pad controls. The device built in regulator for touch sensor. Stable sensing method can cover diversity conditions. Human interfaces control panel links through non-conductive dielectric material. The main application is focused at replacing of the mechanical switch or button. The ASSP can independently handle the 1 touch pad with 1 direct CMOS output pin and 1 open drain output pin that has diode protective circuit. FEATURES  Operating voltage 2.4V~5.5V  Built-in regulator  Operating current, @VDD=3V no load At low power mode typical 2uA, At fast mode typical 6.
