WS2814C 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 | OUTR | output | Red channel constant-current LED driver output carrying the PWM control, with a channel withstand voltage of 20 V. |
| 2 | OUTG | output | Green channel constant-current LED driver output carrying the PWM control, with a channel withstand voltage of 20 V. |
| 3 | OUTB | output | Blue channel constant-current LED driver output carrying the PWM control, with a channel withstand voltage of 20 V. |
| 4 | GND | power_in | Ground for data and power, the VSS = 0 V reference. |
| 5 | DOUT | output | Control data output that passes the reshaped data to the next cascaded IC, with a minimum low-level output current of 10 mA at Vo = 0.4 V. |
| 6 | DIN | input | Control data input from the controller, with a high-level input of at least 0.7VDD and a low-level input of at most 0.3VDD. |
| 7 | VDD | power_in | Logic and IC power supply; absolute maximum rating is +3.7 V to +5.3 V, with 4.5 V to 5.5 V specified for electrical characteristics. |
| 8 | OUTW | output | White channel constant-current LED driver output carrying the PWM control, with a channel withstand voltage of 20 V. |
