A1569E Description
The A1569E is a highly integrated solution that bines 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 ponents and one or more LEDs, the A1569E forms a plete, magnetically actuated lighting solution that is small, flexible, elegant, easy to design, rugged, and reliable. It is optimized for automotive interior...
A1569E Key Features
