AL5809-25QP1-7

Overview

The AL5809-25QP1-7 is a linear LED driver IC from Diodes Incorporated, designed for high-voltage applications. It features a fixed output current of 25 mA and supports an input voltage range from 2.5 V to 60 V. The device operates within a frequency range of 100 Hz to 200 Hz and provides PWM dimming capability. It is housed in a PowerDI-123-2 package and is qualified under AEC-Q100 standards for automotive reliability. The component functions as a two-terminal linear driver with a maximum operating temperature of +125°C.

Feature Summary

• Two-terminal linear topology simplifies circuit design by eliminating external inductors
• Integrated PWM dimming control for precise brightness adjustment
• AEC-Q100 qualification ensures suitability for automotive environments

Applications

• Automotive interior lighting systems
• High-voltage LED string drivers
• Industrial indicator lighting

Procurement Notes

Verify the specific suffix 'QP1' confirms AEC-Q100 automotive qualification status against the official datasheet. Ensure the ordering part number matches the required 25 mA output current variant. Confirm package type is PowerDI-123-2. Cross-reference manufacturer documentation for any recent revisions that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a simple two-terminal solution is required for high-voltage LED strings. It is appropriate for designs needing fixed current regulation without complex feedback networks. Consider the 25 mA output limit and 60 V maximum voltage rating to ensure compatibility with the target LED load configuration and supply voltage constraints.

Part Context

This part belongs to the AL5809 series of linear LED drivers from Diodes Incorporated. The series offers various fixed current options tailored for different LED intensity requirements. The AL5809 family is characterized by its high-voltage tolerance and compact PowerDI packaging, making it suitable for space-constrained high-density lighting applications across industrial and automotive sectors.

Replacement Considerations

Check for other AL5809 variants with different current ratings if 25 mA is insufficient. Verify equivalent two-terminal linear drivers from other manufacturers only if they match the 60 V max voltage and PowerDI-123-2 footprint.
