The TTP111 is a touch detector IC for the DC LED lightings with NMOS application
Operating voltage typical 5.0V
Operating current @VDD=5.0V, 25℃ no load <500uA
Higher frequency 4.8KHz 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
TTP111 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.
