MAX16928AGUP/V+

MAX16928AGUP/V+ is an automotive-grade, multi-channel LED driver IC designed for vehicle lighting. It delivers regulated current to multiple LED strings from a wide automotive power input, with per-channel current adjustment, protection (overvoltage, overcurrent, reverse battery, LED open/short), thermal management, and dimming/diagnostic features. It uses a high-efficiency switching regulator to drive LEDs and provides fault reporting to the host controller. The AGUP/V+ suffix indicates automotive-grade qualification and packaging options. Common applications include tail/brake lights, interior lighting, and other exterior/indoor vehicle illumination. For exact electrical specs, pinout, and programming details, consult the MAX16928 datasheet.
