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
 Operating voltage typical 5.0V
 Operating current @VDD=5.0V, 25Ä no load <500uA
 Higher frequency 2.2KHz PWM output.
 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
 TTP117 PWM output active high control NMOS.
 Two input dimmer modes: touch plate and switch
 The application circuit is simple and easy.
 Can use wire to connect the IC to touch plate.
APPLICATION
 LED LAMP
 For PWM control input
