al5809q document number: ds38233 rev. 1 - 2 4 of 12 www.diodes.com march 2016 ? diodes incorporated advanced informaton al5809q new product application information description the al5809q is a constant current l inear led driver that can be connected on the high side or low side of the leds as a constant current regulato r (ccr) . the al5809q is available in various output current options from 15 ma up to 150ma . the al5809q contains a low dropo ut regulator which provides power to the internal c urrent regulation control block. a fixed preset led current setting resistor sets the reference current of the c urrent regulation block. the led current setting resistor varies with each variant of the al5809. an accurate current mirror within the c urrent 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 ( s ee figure 2 ) . t he minimum system input voltage can be calculated by : v in(min) = v led_chain + 2 .5v where v led_chain is the led chain voltage and 2.5v is the minimum v io(out) voltage of the al5809q . the led current can be increased by connecting two or more al5809q in parallel shown in figure 3 . figure 3 higher led current by parallel configuration of al5809q (a) low - side configuration (b) high - side configuration
al5809q document number: ds38233 rev. 1 - 2 5 of 12 www.diodes.com march 2016 ? diodes incorporated advanced informaton al5809q new product application information (continued) power dissipation the maximum ambient temperature range of the al5809 q 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 cu rrent 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. v inout * i led 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 v inout voltage of 2.5v enables the al5809q to drive 2 led in series from the 9v b attery voltage (assuming v led <3.25v). the al5809qs power dissipation under these conditions will be: v inout * i led = 2.5 * i led so for the 20ma al5809 - 20qpi under these conditions this equals: 2.5v * 20ma = 50mw under maximum input conditions (16v) the al5809qs power dissipation will be: v inout * i led = 9.5 * i led 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 f igures 4 and 5 for graphs showing power dissipation and maximum v inout , for different currents and pcb material. maximizing the area and mass of the ground plane and additional vias between the pad of the out p in will improve the thermal impedance ( ? ja ) of the al5809q. figure 4 power dissipation vs. ambient temperature @ t j = + 150 c figure 5 maximum v inout vs. ambient temperature @ t j = + 150 c
