Diodes’ AL5810Q 60 V adjustable current up to 200 mA linear LED driver offers excellent stability


Diodes Incorporated introduces the AL5810Q, an automotive AEC-Q100 linear LED driver offering an excellent temperature and voltage-current stability with output-adjustable handling capability. The device simplifies the design of LED drivers by setting the LED current with an external resistor using standard value resistors. The AL5810Q has an open-drain output that can swing from 2.0 V up to 60 V supply voltage enabling it to drive long LED chains for high side or low side LED strings. Its low 0.5 VRSET pin is outside of the LED current path and can maintain current accuracy while minimizing the required overheads to regulate the LED current reducing power dissipation. It makes it ideal for driving LEDs up to 200 mA. The AL5810Q is available in the wettable flank W-DFN2020-3/SWP (Type A) package (2 mm x 2 mm), power dissipation (PD) up to 2 W, and has been qualified to AEC-Q100 Grade-2 with automotive compliant supporting PPAPs available.
