TTP117-BD8

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.
