TTP224N-ASD
Overview
The TTP224N-ASD TonTouchTM IC is capacitive sensing design specifically for touch pad controls. The device built in regulator for touch sensor.
- 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
