Model：TTP117-CO8
Package：SOP8
TTP117 is a touch control chip of LED dimming applications
Typical working voltage 5.0 V
VDD = 5.0 V, 25 ℃ when no load working current < 500 ua
2.2 KHz high frequency PWM output, and the light is not flashing
Provide function of two feet, 4 kinds of dimmer mode
(1) 3 period of dimmers, initial to OFF (OFF). OPT2 = 0, OPT1 = 1
(2) 4 period of dimmers, initial to OFF (OFF). OPT2 = 1, OPT1 = 0
(3) 3 period of dimmers, initialization for (ON) (6%). OPT2 = 0, OPT1 = 0
(4) (toggle) ON/OFF switch mode, initial to OFF (OFF). OPT2 = 1, OPT1 = 1
High level motion control NMOS TTP117 PWM output
Two input dimmer mode: touch the induction and the traditional buttons.
Application circuit is simple and easy
Metal lamp body or touch version can through wires connected to the IC feet, good light body design.
LED lights.
Used for PWM control input
