LED Driver IC Procurement Notes

Verify the specific suffix 'S1' confirms the SOD-123 package and 25 mA current setting against the official datasheet. Confirm AEC-Q100 compliance requirements match your target application standards. Ensure thermal management design accounts for the 1.2 W power dissipation limit in the selected operating environment.

LED Driver IC Selection Notes

Select this part when a fixed 25 mA drive current is required for LED strings powered by voltages up to 60 V. The SOD-123 package is ideal for space-constrained designs. Consider the linear topology's efficiency implications compared to switching alternatives if heat dissipation is a primary constraint.

LED Driver IC Part Context

This component belongs to the AL5809 series of two-terminal LED drivers. The series provides various fixed current options and packaging variants to suit different LED load requirements. The AL5809-25S1-7 specifically targets applications needing moderate current levels in a compact surface-mount footprint.

LED Driver IC Replacement Considerations

Check for other AL5809 variants with different current ratings (e.g., 15 mA, 50 mA) or packages (e.g., PowerDI-123-2) if electrical parameters do not match exactly. Verify pinout compatibility before substituting with similar linear LED drivers from other manufacturers.
