TTP224N-ASD - 4 KEY TOUCH PAD DETECTOR

Description

The TTP224N-ASD 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.

Features

  • 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.

Preliminary TTP224N-ASD TonTouchTM 4 KEY TOUCH PAD DETECTOR IC GENERAL DESCRIPTION The TTP224N-ASD 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 4 touch pads with 4 direct output pins. FEATURES  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.
