A1569K

A1569K Automotive 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) Qualified per AEC-Q100 for automotive applications 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 125ºC ambient temperature range Small 8-pin SOIC package with thermal pad PACKAGE: 8-Pin SOICN with Exposed Thermal Pad (Suffix LJ) Not to scale 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. With the addition of only two passive components and one or more LEDs, the A1569K 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 lighti...
