Overview
The AL5809-25S1-7 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 PWM dimming control. The device operates with an input voltage range of 2.5 V to 60 V and withstands up to 60 V output voltage. Packaged in the SOD-123 surface-mount format, it offers a power dissipation capacity of 1.2 W. The component is qualified under AEC-Q100 standards for automotive reliability and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrated high-voltage linear topology suitable for direct AC/DC or isolated DC sources
- Supports precise PWM dimming for adjustable brightness control
- Automotive-grade qualification ensures robust performance in demanding environments
Applications
- LED lighting modules requiring constant current regulation
- Automotive interior and exterior illumination systems
- General-purpose high-voltage LED string drivers
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.
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.
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.
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.
