TTP224N-BSB - 4 KEY TOUCH PAD DETECTOR

Description

The TTP224N-BSB 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.
  • 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 or toggle mode、CMOS output or open.
