AL5809Q AUTOMOTIVE COMPLIANT 60V Two Terminal Constant Current LED Driver PowerDI INFORMATON ADVANCED NEW PRODUCT 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 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.

AL5809Q Document number: DS38233 Rev. 1 - 2 3 of 12 www.diodes.com March 2016 © Diodes Incorporated AL5809Q Application Information INFORMATON ADVANCED NEW PRODUCT 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. (a) (b) Low-Side Configuration High-Side Configuration Figure 3 Higher LED Current by Parallel Configuration of AL5809Q AL5809Q Document number: DS38233 Rev. 1 - 2 4 of 12 www.diodes.com March 2016 © Diodes Incorporated AL5809Q Application Information (Continued) INFORMATON ADVANCED NEW PRODUCT 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 and additional vias between the pad of the Out Pin will improve the thermal impedance (JA) of the AL5809Q.

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. a) PWM Dimming by External MOSFET 200Hz 500Hz 1KHz 1.5KHz b) PWM Dimming by Power Supply VIN ON/OFF Figure 6 PWM Dimming 200Hz 2KHz 90 150 80 135 500Hz 1KHz 1.5KHz 120 LED Current [mA ] 70 LED Current [mA] 60 50 40 30 20 105 90 75 60 45 30 VInOut=3V, 90mA 10 VInOut=3V, 150mA 15 0 0 0 10 20 30 40 50 60 70 80 90 0 100 10 20 30 40 50 60 70 80 90 100 Duty Cycle [%] Duty Cycle [%] Figure 7 PWM Dimming 90mA vs. Duty Cycle 200Hz Figure 8 PWM Dimming 150mA vs. Duty Cycle 500Hz 1KHz 1.5KHz 9 8 LED Current [mA] INFORMATON ADVANCED NEW PRODUCT PWM Dimming 7 6 5 4 3 2 VInOut=3V, 150mA 1 0 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 Duty Cycle [%] Figure 9 Zoomed-In with Duty Cycle ≤5% of Figure 8 AL5809Q Document number: DS38233 Rev. 1 - 2 6 of 12 www.diodes.com March 2016 © Diodes Incorporated AL5809Q Typical Performance Characteristics (15mA, 20mA, 30mA, 40mA, 50mA Options) 15mA 20mA 25mA 30mA 40mA 50mA LED Current [mA] LED Current [mA] 20mA 25mA 30mA 40mA 50mA 60 50 40 30 20 10 TA=25 50 TA = 25°C 40 30 20 10 0 0 0 5 10 15 20 25 30 0 0.5 1 1.5 VInOut [V] 15mA 20mA 25mA 30mA 40mA 50mA 15mA_25C LED Current Accuracy [%] 50 40 30 20 10 0 -25 -10 5 20 35 50 2.5 3 Figure 11 Startup Minimum Operating Voltage 60 -40 2 VInOut [V] Figure 10 LED Current vs. VINOUT LED Current [mA] INFORMATON ADVANCED NEW PRODUCT 60 15mA 65 80 95 15mA_125C 15mA_-40C 10 8 6 4 2 0 -2 -4 -6 -8 -10 110 125 0 5 10 15 20 25 Temperature [⁰C] 30 35 40 45 50 55 60 VInOut [V] Figure 12 LED Current vs. Ambient Temperature Figure 13 LED Current Accuracy (%) vs. VINOUT Across Temperature T_Shut Down T_Recovery T_Recovery 25 20 15 10 5 LED Current [mA] VInOut=3.5V 20mA 0 45 40 35 30 25 20 15 VInOut= 10 3.5V, 40mA 5 0 -5 100 105 110 115 120 125 130 135 140 145 150 155 160 LED Current [mA] -5 100 105 110 115 120 125 130 135 140 145 150 155 160 Ambient Temperature [⁰C] Ambient Temperature [⁰C] Figure 15 THSD of 40mA Current Option Figure 14 THSD of 20mA Current Option AL5809Q Document number: DS38233 Rev. 1 - 2 T_Shut Down 7 of 12 www.diodes.com March 2016 © Diodes Incorporated AL5809Q Typical Performance Characteristics (Continued) (60mA, 90mA, 150mA Options) 90mA 60mA 150mA 160 160 140 140 120 120 LED Current [mA] INFORMATON ADVANCED NEW PRODUCT 60mA 100 80 60 40 90mA 150mA 100 80 60 40 TA=25⁰C LED Current [mA] TA=25⁰C C 20 0 0 5 10 15 20 20 0 25 0 30 0.5 1 1.5 2 2.5 3 VInOut [V] VInOut[V] Figure 17 Startup Minimum Operating Voltage Figure 16 LED Current vs. VInOut VInOut=3.5 Temperature[⁰C] Figure 18 LED Current across Temperature T_Shut Down Figure 19 LED Current Accuracy (%) vs. VINOUT across Temperature T_Recovery T_Recovery 70 60 VInOut=3.5V 60mA 50 40 30 20 10 VInOut=3.5V 150mA LED Current [mA] LED Current [mA] 0 -10 100 160 140 120 100 80 60 40 20 0 -20 100 T_Shut Down 110 120 130 140 150 160 130 140 150 160 Figure 21 THSD of 150mA Current Option Figure 20 THSD of 60mA Current Option Document number: DS38233 Rev. 1 - 2 120 Temperature [⁰C] Ambient Tempature [⁰C] AL5809Q 110 8 of 12 www.diodes.com March 2016 © Diodes Incorporated AL5809Q INFORMATON ADVANCED NEW PRODUCT Ordering Information (Note 12) Part Number LED Current Package Opion Code Packaging 7” Tape and Reel Part Number Quantity Suffix Qualification (Note 13) AL5809-15QP1-7 15mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-20QP1-7 20mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-25QP1-7 25mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-30QP1-7 30mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-40QP1-7 40mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-50QP1-7 50mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-60QP1-7 60mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-90QP1-7 90mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-100QP1-7 100mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-120QP1-7 120mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant AL5809-150QP1-7 150mA P1 PowerDI123 (Type B) 3,000 -7 Automotive Compliant Notes: 12.
