LP8866SQRHBRQ1 is a 32-pin automotive six-channel LED backlight driver with external boost or SEPIC control, PWM/I2C dimming, and up to 150 mA per LED current sink.

Best for

  • Automotive LED display backlighting
  • Six-string LED backlight systems
  • Infotainment, cluster, smart-mirror, and HUD backlights

Avoid if

  • A fully integrated power stage is required
  • The design cannot accommodate external boost/SEPIC components
  • A package with an output-discharge pin is mandatory

Check before use

  • Verify external MOSFET gate-drive arrangement and charge-pump configuration.
  • Validate boost or SEPIC compensation, output capacitance, and switching-current limits.
  • Confirm all unused OUTx pins are tied to GND.
