DIODES AL5809-150QP1-7

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. The AL5809Q is available in the thermally robust PowerDI123 (Type B) package. The AL5809Q has been qualified to AEC-Q100 and is Automotive Compliant supporting PPAPs. 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.
