TTP229-AQG - 16 KEYS OR 8 KEYS TOUCH PAD DETECTOR IC

Description

The TTP229-AQG 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 2.5uA for 16 input keys => Typical 2.0uA for 8 input keys.
  • Provides to set 8 direct keys or 16 direct keys by option.
  • Provides to set 8 separate outputs only for 8 direct input keys mode.
  • Has two kinds of serial output interface, both can use for 8 and 16 direct input keys mode Include 2-wires serial interface and I2C-bus slave interface, they.

Preliminary TTP229-AQG TonTouchTM 16 KEYS OR 8 KEYS TOUCH PAD DETECTOR IC GENERAL DESCRIPTION The TTP229-AQG 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 or up to 16 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 2.5uA for 16 input keys => Typical 2.
