AL5809Q
AUTOMOTIVE COMPLIANT 60V TWO TERMINAL CONSTANT CURRENT LED DRIVER
PowerDI123 (Type B)
Description
Pin Assignments
The AL5809Q is a constant current linear LED driver that provides a
cost-effective two-pin solution to LED driving. It has an excellent
temperature stability of 20ppm/°C with tight 5% current accuracy
over a wide voltage and temperature range. The AL5809Q comes in
various fixed output current versions removing the need for external
current setting resistors creating a simple solution for the linear
driving of LEDs. It supports both the high-side and low-side driving of
LED chains.
The AL5809Q turns on after a short delay once the voltage across its
terminals reaches approximately 1.5V. Its maximum 60V voltage
rating between input and output pins enables it to withstand high
peak transient voltages that can occur in automotive applications.
The AL5809Q is available in the thermally robust PowerDI®123 (Type
B) package. The AL5809Q has been qualified to AEC-Q100 and is
Automotive Compliant supporting PPAPs.
