DIODES AL5809-15S1-7

The AL5809 is a constant current linear LED driver and it provides a cost - effective two pin solution. It has an excellent temperature stability of 20 ppm/℃ and the current accuracy ±5% regulated over a wide voltage and temperature range. The AL5809 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 AL5809 turns on when the voltage between IN and OUT swings from 2.5 V up to 60V enabling it drive long LED chains. The floating ground, 60V Voltage rating between Input and Output pins designed to withstand the high peak voltage incurred in offline applications. The AL5809 is available in either thermally robust package PowerDI123 or SOD - 123 package. The AL5809 is a constant current Linear LED driver and can be placed in series with LEDs as a High Side or a Low Side constant current regulator. The AL5809 offers various current settings from 15mA up to 150 mA and different current settings available upon request. The AL5809 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 increases the reference current to the preset LED current of the AL5809.
