TTP117-CO8N from Tontek Design Tech, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CK | input | System clock input pin; an R_CK of 120K to set the oscillator (Fosc about 1.2MHz at VDD=5.0V) is shown in the application circuit. |
| 2 | VDD | power_in | Positive power supply, operating 3.6V to 6.8V (typ. 5.0V), absolute maximum VSS+5.5V. |
| 3 | TI | input | Touch input (switch mode I-PH) with an internal pull-high resistor of about 300K at VDD=5.0V. |
| 4 | CI | input | Sensor control input for the touch detection circuit. |
| 5 | OPT2 | input | Dimmer mode select input with internal pull-low resistor (about 130K), combined with OPT1 to choose one of 4 dimmer modes. |
| 6 | VSS | power_in | Negative power supply, system ground. |
| 7 | OPT1 | input | Dimmer mode select input with internal pull-high resistor (about 140K), combined with OPT2 to choose one of 4 dimmer modes. |
| 8 | AT | output | PWM output controlling an NMOS, active high, about 2.2KHz at Fosc=1.2MHz; sink 12mA min and source 4mA min at VDD=5.0V. |
