TTP117
TOUCH DIMMER
FOR LED LIGHTING


GENERAL DESCRIPTION
The TTP117 is a touch detector IC for the LED lightings with NMOS application.
function controls by PWM output. It has high frequency for PWM output.


FEATURES
The dimmer
ƒ Operating voltage typical 5.0V
ƒ Operating current @VDD=5.0V, 25Ċ no load <500uA
ƒ Higher frequency 2.2KHz PWM output.
ƒ Support two option pin to select 4 type dimmer modes.
(1). 3 steps dimmer initial OFF. OPT2=0, OPT1=1
(2). 4 steps dimmer initial OFF. OPT2=1, OPT1=0
(3). 3 steps dimmer initial ON (6%). OPT2=0, OPT1=0
(4). Toggle ON / OFF initial OFF. OPT2=1, OPT1=1
ƒ TTP117 PWM output active high control NMOS.
ƒ Two input dimmer modes: touch plate and switch
ƒ The application circuit is simple and easy.
ƒ Can use wire to connect the IC to touch plate.


APPLICATION
ƒ LED LAMP
ƒ For PWM control input
