AL5809-100QP1-7

Overview

The AL5809-100QP1-7 is a linear LED driver IC from Diodes Incorporated, designed for constant current regulation. It features a single output with a maximum current of 100 mA and supports PWM dimming. The device operates within an input voltage range of 2.5 V to 60 V, delivering up to 60 V output voltage. It is housed in a PowerDI-123-2 package and certified to AEC-Q100 standards for automotive applications. Operating temperatures span from -40°C to +85°C.

Feature Summary

• Provides stable constant current regulation for LED loads
• Supports external PWM dimming control for brightness adjustment
• Automotive-grade reliability compliant with AEC-Q100 standards

Applications

• Automotive interior lighting systems
• Dashboard illumination circuits
• General-purpose LED indicator drivers

Procurement Notes

Verify the specific suffix QP1-7 confirms the 100 mA current setting and PowerDI-123-2 packaging. Confirm AEC-Q100 qualification status is required for your target application. Ensure the supplier provides official datasheets matching the Diodes Incorporated part number to avoid counterfeit components.

Selection Notes

Select this component when a linear topology is preferred for low-noise LED driving in automotive environments. The 100 mA output rating suits standard indicator LEDs. Consider thermal dissipation requirements given the linear nature of the driver at higher voltage differentials.

Part Context

This part belongs to the AL5809 series of linear LED drivers. Variants in the series differ primarily by output current ratings (e.g., 15 mA, 25 mA, 40 mA) and package types (SOD-123-2 vs. PowerDI-123-2). The QP1-7 suffix denotes the specific 100 mA configuration with automotive qualification.

Replacement Considerations

Direct substitutes include other AL5809 variants with adjusted current ratings if lower drive capability is acceptable. Cross-reference with similar linear LED drivers from other manufacturers only if pin compatibility and electrical specifications match exactly.
