Overview
The AL8806QMP-13 is an automotive-grade buck LED driver IC manufactured by Diodes Incorporated. It operates with a supply voltage range of 4.5 V to 40 V and delivers a regulated output current of 1.5 A. The device features a fixed switching frequency of 250 kHz and supports PWM dimming for brightness control. It includes open LED protection and is housed in an MSOP-8 package. Qualified under AEC-Q100 standards, it functions reliably within a temperature range of -40 °C to +125 °C.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards
- Integrated high-side switch for efficient buck topology operation
- Supports pulse-width modulation (PWM) dimming for precise brightness adjustment
- Includes open LED protection circuitry for enhanced system safety
Applications
- Automotive interior lighting systems
- LED ambient lighting modules
- Constant current LED driving circuits
- Buck converter based LED illumination designs
Procurement Notes
Verify the specific suffix 'QMP' confirms the MSOP-8 EP package and tape-and-reel quantity as documented in the official datasheet. Confirm AEC-Q100 qualification status aligns with project requirements. Ensure compatibility with the specified 4.5 V to 40 V input range and 1.5 A output capability. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit components.
Selection Notes
Select this component for applications requiring a single-channel constant current source with integrated switching capabilities. It is suitable for designs needing PWM dimming control without external logic. Consider the thermal performance of the MSOP-8 package for heat dissipation needs. Verify that the required output current does not exceed the 1.5 A limit under all operating conditions.
Part Context
This part belongs to the AL8806 family of high-efficiency LED drivers from Diodes Incorporated. The 'Q' prefix typically denotes automotive grade qualification, while 'MP' indicates the specific MSOP-8 EP packaging variant. It is designed to replace discrete solutions or older generation drivers in compact automotive lighting assemblies.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer's portfolio that share the MSOP-8 EP footprint. Verify if other parts in the series offer different switching frequencies or current ratings that might better suit specific thermal constraints.
