Description

The AL5810Q is an automotive AEC-Q100 linear LED driver offering an excellent temperature and voltage current stability with output adjustable handling capability. The AL5810Q 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 2.0V up to 60V supply voltage enabling it to drive long LED chains for highside or low-side LED strings. Its low 0.5V RSET pin is outside of the LED current path and can maintain current accuracy while minimizing the required overheads to regulate the LED current. This reduces its power dissipation when compared to traditional linear LED drivers. It makes it ideal for driving LEDs up to 200mA.

The AL5810Q is available in the wettable flank W-DFN2020-3/SWP (Type A) (2mm x 2mm) package featuring power dissipation (PD) up to 2W and TO252 (DPAK) package with PD up to 3.85W. The AL5810Q is qualified to AEC-Q100 Grade 2 with automotive compliance supporting PPAPs.
