8022W from Sam wing, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect. Leave floating on the PCB. |
| 2 | CMOD | passive | Charge-share sampling capacitor input. Connect an NPO cap to GND (10 nF typ.; 33 nF for direct metal-shell touch, 10/20/47 nF for acrylic glass 3/3-6/6-10 mm) to set touch sensitivity. |
| 3 | VDD | power_in | Positive supply, 2.4-5.5 V (absolute max 6.0 V). Bypass with 10 µF + 0.1 µF to VSS. |
| 4 | VSS | power_in | Ground / negative supply reference. |
| 5 | KEY | input | Capacitive touch sense input. Connects through a series resistor (Rt ≈ 1 kΩ) to the touch pad/electrode; short-press toggles on/off, long-press ramps brightness. |
| 6 | OPT1 | input | Mode-select option 1, sampled at power-up. Internal pull-up: float = 1, tie to GND = 0. Combined with OPT2 to pick one of four dimming modes (see Table 2). |
| 7 | OUT | output | 20 kHz PWM output driving the LED (typ. via a series resistor + NPN low-side switch). Source ≈ −4.5 mA @ VOH=0.9·VDD; Sink ≈ 12 mA @ VOL=0.1·VDD (VDD=5 V). Duty range 2-100% (mode 4: 10/40/100%). |
| 8 | OPT2 | input | Mode-select option 2, sampled at power-up. Internal pull-up: float = 1, tie to GND = 0. Combined with OPT1 to pick one of four dimming modes (see Table 2). |
