AL58812Q

AL58812Q is a Diodes Incorporated 12-channel linear LED driver in a W-QFN5050-40 package — the mid-count member of the AL588 automotive lighting platform, sourcing up to 70 mA per channel with 12-bit, 30 kHz PWM dimming for smooth, flicker-free lamp animation. The supply range is 2.7 V to 5.5 V with I2C or SPI control, and the device is AEC-Q100 Grade 1 qualified and PPAP capable. Order as AL58812QFRZW40-13; the FRZW40-13 suffix is the orderable wettable-flank package and reel form of the base device name. Selection advice: choose this 12-channel version when a lamp function — a turn-indicator segment group or a daytime-running-light strip — fits within twelve strings; the AL58818Q on this site adds six more channels on the same control architecture for larger clusters, so firmware and layout concepts carry over when a design grows. As a linear driver it dissipates the voltage headroom times string current as heat: keep per-string headroom as low as LED binning allows.
