Overview
The AL8871QT16E-13 is a Buck-Boost LED controller from Diodes Incorporated, designed for automotive applications. It operates within an input voltage range of 5 V to 60 V and supports output currents up to 18 mA. The device integrates step-down (buck) and step-up (boost) capabilities with a switching frequency between 300 kHz and 1 MHz. It features analog and PWM dimming control and functions reliably across a junction temperature range of -40 °C to +125 °C.
Feature Summary
- Integrates buck and boost DC/DC conversion topologies for flexible LED drive configurations
- Supports mixed analog and PWM dimming methods for precise light control
- Automotive-grade reliability compliant with AEC-Q100 standards
Applications
- Automotive interior lighting systems
- Ambient LED illumination circuits
- Low-power LED driver designs requiring wide input voltage tolerance
Procurement Notes
Verify the specific part number against official Diodes Incorporated documentation to confirm the Buck-Boost topology and 18 mA output rating. Ensure the ordering suffix matches the required tape and reel packaging specifications. Cross-reference the AEC-Q100 qualification status if automotive compliance is mandatory for the target application.
Selection Notes
Select this component when a single-channel controller must handle both step-up and step-down voltage requirements in automotive environments. The integrated Buck-Boost architecture simplifies design by eliminating external topology switching components. Verify that the 18 mA current limit aligns with the specific LED string requirements before finalizing the schematic.
Part Context
This part belongs to the AL8871Q series of automotive LED drivers manufactured by Diodes Incorporated. The 'T16E' designation indicates a 16-pin TSSOP package with an exposed pad for thermal management. The '-13' suffix typically denotes the standard tape and reel packaging configuration used for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official cross-reference tools or datasheet footnotes for verified alternatives.
