TTP112 - CONTINUOUS TOUCH DIMMER

General Description

The TTP112 is a continuous touch detector IC for the DC LED lightings.

controls by PWM output.

The PWM duty range is 3% ~98% that is the lighting dimmer as 3% ~98%.

Key Features

  • Operating voltage 4.5V ~6.8V.
  • Operating current < 1.2mA @VDD=5.0V, no load.
  • Support two output mode : (1) PWM Dim Mode, (2) Direct/Toggel Mode.
  • Small adjusts duty rate 0.2%.
  • Support two dimmer speeding as 6 sec and 12 sec lightness circulation.
  • PWM output control NMOS or Direct output mode.
  • Memorize turn on.
  • Two turn off modes: delay off and non-delay off.
  • Two input dimmer modes: touch plate and switch.
  • Two dimmer mode Cycle and Non-Cycle.

Patent No.: M371298 (Taiwan) ZL 2010 2 0300629.5 (CHINA) TTP112 CONTINUOUS TOUCH DIMMER FOR DC LED LIGHTING GENERAL DESCRIPTION The TTP112 is a continuous touch detector IC for the DC LED lightings. The dimmer function controls by PWM output. The PWM duty range is 3% ~98% that is the lighting dimmer as 3% ~98%. It has high frequency and small adjusts duty rate, which can let the LED lighting dim smoothly. FEATURES ƒ Operating voltage 4.5V ~6.8V ƒ Operating current < 1.2mA @VDD=5.0V, no load ƒ Support two output mode : (1) PWM Dim Mode, (2) Direct/Toggel Mode. ƒ Small adjusts duty rate 0.2%. ƒ Support two dimmer speeding as 6 sec and 12 sec lightness circulation. ƒ PWM output control NMOS or Direct output mode. ƒ Memorize turn on.
