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.

AL5809Q
Application Information
Description
The AL5809Q is a constant current linear LED driver that can be connected on the high side or low side of the LEDs as a Constant Current
Regulator (CCR). The AL5809Q is available in various output current options from 15mA up to 150mA.
The AL5809Q contains a Low Dropout regulator which provides power to the internal current regulation control block. A fixed preset LED current
setting resistor sets the reference current of the current regulation block. The LED current setting resistor varies with each variant of the AL5809.
An accurate current mirror within the current regulation control block then increases the reference current to the preset LED current of the
AL5809Q.
Simple LED String
The number of LEDs that the AL5809Q can drive depends on the forward voltage drop of the LEDs and the input supply voltage (minus the
minimum operating voltage of the AL5809Q). The designer needs to calculate the maximum voltage between In and Out by taking into account
the maximum input voltage less the voltage across the LED string (Figures 1 & 2).
Figure 1 Low-Side LED String Drive
Figure 2 High-Side LED String Drive
The AL5809Q can also be used on the high-side of the LEDs (See Figure 2). The minimum system input voltage can be calculated by:
VIN(MIN) = VLED_CHAIN + 2.5V Where VLED_CHAIN is the LED chain voltage and 2.5V is the minimum VIO(OUT) voltage of the AL5809Q.
The LED current can be increased by connecting two or more AL5809Q in parallel shown in Figure 3.

Application Information (Continued)
Power Dissipation
The maximum ambient temperature range of the AL5809Q is determined by its power dissipation and thermal impedance of the PCB onto which
it is mounted. Its junction temperature must be kept equal to or less than +150°C.
The power dissipated is determined by the LED current version that has been selected (15, 20, 25 30, 40, 50, 60, 90, 100, 120 or 150mA) and
the difference between the input voltage and LED chain voltage.
VINOUT * ILED
In automotive applications the typical input voltage will be around 13V but can vary between 9V (without stop-start operation) and approximately
16V.
The recommended minimum VINOUT voltage of 2.5V enables the AL5809Q to drive 2 LED in series from the 9V battery voltage (assuming
VLED <3.25V).
The AL5809Q’s power dissipation under these conditions will be:
VINOUT * ILED = 2.5 * ILED
So for the 20mA AL5809-20QPI under these conditions this equals:
2.5V * 20mA = 50mW
Under maximum input conditions (16V) the AL5809Q’s power dissipation will be:
VINOUT * ILED = 9.5 * ILED
So for the 20mA AL5809-20QPI this equals:
9.5V * 20mA = 190mW
So there is a large difference in power dissipation of the Linear LED driver between minimum and maximum battery voltages. And care must be
taken to calculate expected power dissipations and then determining the suitable PCB material and layout. See Figures 4 and 5 for graphs
showing power dissipation and maximum VINOUT, for different currents and PCB material. Maximizing the area and mass of the ground plane
with additional vias between the pad of the Out Pin will improve the thermal impedance (JA) of the AL5809Q.

Application Information (Cont.)
PWM Dimming
The AL5809Q can be used to provide LED current dimming driving the Out Pin via an external MOSFET switch to Ground (Figure 6a) for high-
side connected LEDs or a high-side switch for Ground-connected LEDs. The Out Pin current is then effectively switched on and off causing the
LED current to turn on and off. The dimming effect can be achieved by varying the PWM signal duty cycle.
