The device built in regulator for touch sensor.

Stable sensing method can cover diversity conditions.

Preliminary TTP224N-ASD TonTouchTM 4 KEY TOUCH PAD DETECTOR IC GENERAL.

Operating voltage 2.4V~5.5V.
Built-in regulator with external enable/disable option.
Operating current, @VDD=3V no load At low power mode typical 2.5uA, At fast mode typical 9uA.
@VDD=3V operating voltage : The response time about 60mS at fast mode,160mS at low power mode.
Sensitivity can adjust by the capacitance(0~50pF) outside for each touch pad.
Provides Fast mode and Low Power mode selection by pad option(LPMB pin).
Provides direct mode.
