# WS2808

**Worldsemi** · LED Drivers · SOP-8

WS2808 from Worldsemi, 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 | OUT1 | output | PWM constant-current LED drive output for channel 1, with duty cycle set by the 24-bit data latched from the input stream; the datasheet gives a typical 12 mA low-level output current at DC=12 V with FFH data. |
| 2 | OUT2 | output | PWM constant-current LED drive output for channel 2, with duty cycle set by the 24-bit data latched from the input stream; the datasheet gives a typical 12 mA low-level output current at DC=12 V with FFH data. |
| 3 | OUT3 | output | PWM constant-current LED drive output for channel 3, with duty cycle set by the 24-bit data latched from the input stream; the datasheet gives a typical 12 mA low-level output current at DC=12 V with FFH data. |
| 4 | DOUT | output | Cascade data output that retransmits the reshaped serial data to the next chip, with a minimum low-level output current of 10 mA at Vo=0.4 V. |
| 5 | DIN1 | input | Main serial data input receiving the single-wire data stream from the controller, with VIH minimum 2.7 V and VIL maximum 0.7 V. |
| 6 | GND | power_in | Signal and power ground, the common reference for VDD. |
| 7 | DIN2 | input | Secondary (auxiliary) data input, listed in the datasheet with the same DIN electrical limits of VIH minimum 2.7 V and VIL maximum 0.7 V. |
| 8 | VDD | power_in | Logic supply for the IC, specified at 11.5 V to 12.5 V in the electrical test conditions and rated at +9.5 V to +14.5 V as a maximum rating. |
