TTP229-GQD - 8 KEYS TOUCH PAD DETECTOR

Description

The TTP229-GQD 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.
  • Stand-by current At 3V, and sleep mode slow sampling rate 8Hz：=> Typical 2.0uA.
  • Provides I2C-bus slave interface.
  • Offer multi-key or single-key feature by option.
  • Provides two kinds of sampling rate that slow sampling rate 8Hz and fast sampling rate 64Hz at sleep mode.
  • Have the maximum key-on time about 80sec by pin option.
  • Sensitivity can adjust by the capacitance(1~50pF) outside.
  • After power-on have.

Preliminary TTP229-GQD TonTouchTM 8 KEYS TOUCH PAD DETECTOR IC GENERAL DESCRIPTION The TTP229-GQD 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 8 touch pads. FEATURES ƒ Operating voltage：2.4V~5.5V ƒ Built-in regulator ƒ Stand-by current At 3V, and sleep mode slow sampling rate 8Hz：=> Typical 2.
