LED Drivers

18-channel LED driverRGB LED driverI2CSPI16-bit PWMVQFN-32

LP5861RSMR is a 32-pin, 18-channel LED driver suited to individually controlled LED dots and six RGB LEDs, with high-frequency PWM dimming and I2C or SPI communication.

Best for

  • Compact RGB indicator and animation designs
  • Per-LED brightness calibration
  • Keyboard, gaming, appliance, and control-panel lighting

Avoid if

  • The application requires more than 18 independently controlled LED channels from one IC
  • A matrix-scanning architecture with multiple high-side rows is required

Check before use

  • Set the maximum-current register before enabling high-current operation
  • Keep unused CS and SW pins floating as specified
  • Use VSYNC when selecting data refresh Mode 2 or Mode 3
