Description
AL5809Q
AUTOMOTIVE COMPLIANT 60V Two Terminal Constant Current LED Driver
PowerDI
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 immediately and operates with a voltage
across its terminals varying from 2.5V up to 60V, enabling it to drive
long LED chains. The 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 Grade 3
and is Automotive Compliant supporting PPAPs.

Caution:
Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when
handling and transporting these devices.
