SOP8
Product overview
The TTP117-DO8 is a touch-controlled LED dimming application chip that achieves dimming by a PWM-controlled NMOS with a high-frequency PWM output.
Detailed description

Special feature


Typical operating voltage 5.0V ? VDD=5.0V, 25°C operating current without load < 500uA


2.2KHz high frequency PWM output, dimming does not flash


Provides 2 function pins and selects 4 dimming modes


(1) 3-stage dimmer, initially OFF (OFF). 

OPT2 = 0, OPT1 = 1


(2) 4-stage dimmer, initially OFF (OFF). 

OPT2 = 1, OPT1 = 0


(3) 3-stage dimmer, initially ON (6%). 

OPT2 = 0, OPT1 = 0


(4) Switch mode (toggle) ON / OFF, initial OFF (OFF). 

OPT2 = 1, OPT1 = 1 ? TTP117 PWM output high level action control NMOS


Two input dimmer modes: touch sensing and traditional buttons.


Application circuit is simple and easy


The metal body or touch version can be connected to the IC pin by wires, which is beneficial to the lamp body design.





Application range


LED lights.


For PWM control input
