TTP224N-DO8 - 2 KEY TOUCH PAD DETECTOR

Description

The TTP224N-DO8 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 2uA, At fast mode typical 6.5uA.
  • @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 active high or active low by pad option(AHLB pin).
  • Have the maximum on time 16sec/infinite by pad option(MOT0 pin).
  • A.

Preliminary TTP224N-DO8 TonTouchTM 2 KEY TOUCH PAD DETECTOR IC GENERAL DESCRIPTION The TTP224N-DO8 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 2 touch pads with 2 direct output pins. 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.
