WS2814A

Worldsemi · LED Drivers · SOP-8

WS2814A from Worldsemi, 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 OUTR output Red channel constant-current LED driver output. Open-drain low-side sink, typ 16.5 mA (15.5-17.5 mA), withstands up to 20 V on the pin. PWM duty ratio set by the received 8-bit R data.
2 OUTG output Green channel constant-current LED driver output. Open-drain low-side sink, typ 16.5 mA, 20 V withstand. PWM duty ratio set by the received 8-bit G data.
3 OUTB output Blue channel constant-current LED driver output. Open-drain low-side sink, typ 16.5 mA, 20 V withstand. PWM duty ratio set by the received 8-bit B data.
4 GND power_in Data and power ground (VSS = 0 V reference for all logic and output-current returns).
5 DOUT output Cascaded data output to the DIN of the next WS2814A in the chain. Push-pull output, low-level sink ≥10 mA at Vo=0.4 V; transmission delay ≤300 ns (DIN→DOUT, CL=15 pF, RL=10 kΩ). Signal is internally reshaped so cascade length is not limited by waveform degradation.
6 DIN input Single-wire NZR serial data input from MCU or upstream WS2814A's DOUT. VIH ≥ 0.7·VDD, VIL ≤ 0.3·VDD, hysteresis ~0.35 V, input capacitance ≤15 pF. Withstands up to 9 V on the pin. First chip captures the initial 32-bit word into its latch and forwards the remainder to DOUT.
7 VDD power_in Logic power supply, 3.7-5.3 V (recommended 4.5-5.5 V for electrical spec). Built-in voltage regulator allows operation from 12 V or 24 V rails via a series dropping resistor (2.7 kΩ typical for 12 V; 8.2 kΩ for 24 V per the application circuits).
8 OUTW output White channel constant-current LED driver output. Open-drain low-side sink, 20 V withstand. PWM duty ratio set by the received 8-bit W data (transmitted first in the 32-bit WRGB frame).
