Key Document


This reference design details a highly integrated solution for driving LEDs in a CHMSL, which includes brake and reverse lights. Each light is capable of independent function by applying power to its supply line. The design uses three automotive-rated linear LED drivers (TPS92610-Q1) to obtain a low BOM count yet feature-rich solution. The design also includes protection features against load dump conditions and reverse battery conditions while simultaneously maintaining a small solution size.

  • Low bill of materials (BOM) count
  • Highly integrated solution
  • Precision current regulation
  • Optional diagnostic features
  • Reverse battery protection
