A1569K - Automotive LED Driver

General Description

The A1569K is a highly integrated solution that combines a Hall-effect switch with a linear, programmable current regulator, providing up to 150 mA to drive one or more LEDs.

Key Features

  • Linear LED drive current ≤150 mA set by an external reference resistor.
  • High sensitivity, omnipolar Hall-effect switch for LED on/off control.
  • Low component count for small size and ease of design.
  • Elegant fade-in/fade-out effects with adjustable duration (optional).
  • Qualified per AEC-Q100 for automotive.
