AL5810Q
ADJUSTABLE 60V LINEAR LED DRIVER
Description
Pin Assignments
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.
W-DFN2020-3/SWP (Type A)
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 high-
side 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.
