ams OSRAM AS1163 and AS1163B Automotive LED Driver ICs are mixed-signal silicon devices optimized for dynamic lighting applications. These ICs support single-layer slim PCB designs and Open System Protocol (OSP), which makes them compatible with OSIRE E3731i. The AS1163 and AS1163B LED driver ICs feature a 2.4Mbit/s two-wire daisy chain (bi-directional or loop-back) or star topology, up to 1000 nodes, and 16-bit brightness adjustment. The additional features include an I2C gateway, parallel connection, power-rail feedback, and analog readout. These devices are used in interior dynamic lighting effects, ambient lighting, functional lighting, exterior lighting, roof lighting, and smart surfaces.
