Characteristics

Typical operating voltage 5.0V

Operating current is typically less than 500uA at VDD=5.0V, 25°C, no load

Pulse width modulation (PWM) output up to 2.2KHz

4 optional dimming modes (pin OPT1. OPT2 selection):

(1). Level 3 adjustment, initial off. 

OPT2=0, OPT1=1

(2). Level 4 adjustment, initial off. 

OPT2=1, OPT1=0

(3). Level 3 adjustment, initial opening (6%). 

OPT2=0, OPT1=0

(4). Switch mode, initial off. 

OPT2=1, OPT1= 1

TTP117M PWM output high level controls NMOS.

Two dimming input modes: touch and switch.

The application circuit is simple and easy to use.

It can be connected to the touchpad via wires.
