AL5809Q AUTOMOTIVE COMPLIANT 60V TWO TERMINAL CONSTANT CURRENT LED DRIVER PowerDI123 (Type B) ADVANCED INFORMATON 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.

AL5809Q Document number: DS38233 Rev. 2 - 2 4 of 12 www.diodes.com August 2017 (c) Diodes Incorporated AL5809Q Application Information Description ADVANCED INFORMATON 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. (a) (b) Low-Side Configuration High-Side Configuration Figure 3 Higher LED Current by Parallel Configuration of AL5809Q AL5809Q Document number: DS38233 Rev. 2 - 2 5 of 12 www.diodes.com August 2017 (c) Diodes Incorporated AL5809Q Application Information (Continued) Power Dissipation ADVANCED INFORMATON 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 +150C. 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.

ADVANCED INFORMATON 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 highside 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. a) PWM Dimming by External MOSFET b) PWM Dimming by Power Supply VIN ON/OFF Figure 6 PWM Dimming Recommended PWM Frequency and Dimming Range Duty Cycle (%) PWM Frequency (Hz) Minimum Maximum 100 5 95 200 10 90 Test conditions (Figure 6a): PWM frequency 100Hz-200Hz Square wave, 0-4V gate voltage, VIN = 6V, 1 LED, AL5809-30mA Use the following formulae to calculate the Min and Max duty cycle: Min.
