A1569E

A1569E LED Driver with Integrated Hall-Effect Switch FEATURES AND BENEFITS 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) Low dropout voltage and low supply current Chopper-stabilized Hall switch □□Low switchpoint drift over temperature □□Insensitivity to physical stress Input pin for external LED driver control Slew-rate-limited LED output drive for current transient suppression Ruggedness and reliability □□Integrated voltage regulator for operation from 7 to 24 V □□Reverse-battery protection □□Automatic short-circuit and thermal overload protection and recovery □□–40ºC to 85ºC ambient temperature range Small 8-pin SOIC package with thermal pad PACKAGE: 8-Pin SOICN with Exposed Thermal Pad (Suffix LJ) DESCRIPTION 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 lighting solution that is small, flexible, elegant, easy to design, rugged, and reliable. It is optimized for automotive interior and auxilliary lighting such as map lights, glove boxes, consoles, vanity mirrors, hood/truck/bed li...
