LED Drivers

18-channel LED driver125 mA per channelRGB LED driver16-bit PWMI2CSPIVQFN-32

LP5861TRSMR is an 18-channel, high-current LED driver for direct control of up to 18 LEDs or 6 RGB LEDs with analog current control and 8-bit or 16-bit PWM dimming.

Best for

  • 18-channel direct LED drive
  • RGB LED assemblies with up to 6 pixels
  • High-resolution PWM dimming
  • I2C or SPI controlled LED indicators

Avoid if

  • Applications requiring more than 18 directly driven LED channels from one device
  • LED systems where supply voltage cannot maintain LED VF plus driver saturation voltage
  • Designs without adequate thermal PCB area

Check before use

  • Set maximum current from 7.5 mA to 125 mA according to LED and thermal limits
  • Confirm VCC is at least 3.3 V when 125 mA per channel is required
  • Select the intended interface with the IFS pin
  • Use the required local decoupling capacitors and exposed-pad ground connection
