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 20ppm/°C 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 2.5V 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.
This article will introduce AL5809 systematically from its features, pinout to its specifications, applications, also including AL5809 datasheet and so much more.
