A1569E LED Driver

The A1569E 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. With the addition of only two passive components and one or more LEDs, the A1569E forms a complete, magnetically actuated lig.

A1569E 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 (op
