LED Indication - Discrete

RGB LED driver3-channel16-bit PWMconstant currentsingle-wire cascadeSOP-8

WS2913/SOP8 is a three-channel constant-current RGB LED controller for cascaded LED strings, strips, modules, and display lighting. It supports 16-bit RGB PWM when SET is tied to VDD.

Best for

  • Cascaded RGB LED strings and strips
  • Decorative full-color lighting
  • LED modules and display segments

Avoid if

  • A documented RoHS, REACH, MSL, or lifecycle status is mandatory and cannot be separately confirmed
  • The controller cannot generate the specified single-wire timing and reset interval

Check before use

  • Tie SET to VDD for 16-bit grayscale operation
  • Confirm LED string voltage and output dissipation
  • Validate data timing against the datasheet electrical limits
