AL5816QW5-7

Overview

The AL5816QW5-7 is a linear LED controller manufactured by Diodes Incorporated, designed for single-output LED lighting applications. It operates within an input voltage range of 4.5 V to 60 V and supports a maximum output current of 10 mA. The device features PWM dimming capability and is qualified under AEC-Q100 standards for automotive reliability. It functions across an extended temperature range from -40 °C to +125 °C and is housed in a compact SOT-25-5 surface-mount package.

Feature Summary

• Supports PWM dimming for precise light control
• AEC-Q100 qualified for automotive-grade reliability
• Wide input voltage tolerance up to 60 V

Applications

• Automotive interior LED lighting systems
• General-purpose LED indicator circuits
• Low-power LED driver designs requiring linear regulation

Procurement Notes

Verify the specific suffix QW5-7 against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure the design accounts for thermal dissipation limits inherent to linear topologies at higher voltage differentials. Confirm AEC-Q100 qualification status if deploying in automotive environments. Cross-reference RoHS compliance requirements with project specifications before finalizing procurement.

Selection Notes

Select this component when a simple, low-cost linear solution is preferred over switching regulators for small LED arrays. It is suitable for applications where electromagnetic interference (EMI) must be minimized and input voltages remain stable within the 4.5 V to 60 V window. Consider the 10 mA current limit when sizing LED strings or parallel branches.

Part Context

This part belongs to the AL5816 series of linear LED drivers from Diodes Incorporated. It shares functional similarities with other members like the AL5815 but differs in specific current ratings and internal configurations. The series targets cost-sensitive LED applications requiring robust performance in varying supply conditions.

Replacement Considerations

Direct substitutes may include other parts from the AL581x family, such as the AL5815, provided current and voltage parameters align with the design requirements. Verify pin compatibility and thermal characteristics before substitution.
