AL5809-90QP1-7

Overview

The AL5809-90QP1-7 is a linear LED driver IC from Diodes Incorporated, designed for two-terminal AC/DC applications. It delivers a regulated output current of 94.5 mA with a maximum output voltage of 60 V and input voltage range from 2.5 V to 60 V. The device supports PWM dimming at frequencies between 100 Hz and 200 Hz, operates within -40 °C to +125 °C, and features AEC-Q100 automotive qualification in the PDI-123 package.

Feature Summary

• Two-terminal architecture enabling direct replacement for incandescent lamps without external control circuitry
• Integrated high-voltage switch supporting wide input voltage ranges for universal AC/DC compatibility
• Precision constant current regulation ensuring stable LED brightness under varying line conditions

Applications

• Direct replacement for incandescent bulbs in retrofit lighting fixtures
• Automotive interior and exterior illumination systems requiring AEC-Q100 compliance
• General-purpose LED downlights and spotlights utilizing two-terminal sockets

Procurement Notes

Verify the suffix 'QP1' indicates automotive-grade AEC-Q100 qualification distinct from standard variants. Confirm the specific output current rating matches design requirements, as the datasheet specifies 94.5 mA for this part number despite some listings referencing 90 mA. Ensure the PowerDI-123 package footprint aligns with PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when designing two-terminal LED replacements that require automotive reliability standards. The integrated high-voltage switch simplifies schematic design by eliminating external switching components. Consider thermal dissipation capabilities within the compact PowerDI-123 package, as power handling is limited compared to larger packages or active topologies.

Part Context

This part belongs to the AL5809 series of linear LED drivers manufactured by Diodes Incorporated. The series offers various fixed current options tailored for different LED power requirements while maintaining a consistent two-terminal form factor. The AL5809 family is engineered for cost-effective, high-reliability lighting solutions across residential, commercial, and automotive sectors.

Replacement Considerations

AL5809-90P1-7 serves as the non-automotive grade equivalent with identical electrical characteristics but without AEC-Q100 certification.
