Overview
The AL8807BQMP-13 is a buck LED driver from Diodes Incorporated, designed for 12V and 24V automotive lighting systems. It integrates a power MOSFET and operates at frequencies up to 1MHz. The device supports PWM dimming and sets output current via an external resistor. Key electrical parameters include a 6V to 36V input voltage range, a maximum output voltage of 40V, and a continuous output current of 1.3A. It features open LED protection and operates within a junction temperature range of -40°C to 125°C. The component is AEC-Q100 qualified and housed in an 8-pin MSOP package.
Feature Summary
- Integrates a power switch for simplified circuit design
- Supports high-frequency operation up to 1MHz
- Enables precise current regulation via external sensing resistor
- Includes built-in open LED protection
Applications
- Automotive MR16 LED lamps
- 12V DC LED lighting systems
- 24V DC LED lighting systems
- General-purpose step-down LED drivers
Procurement Notes
Verify the specific suffix 'QMP' confirms AEC-Q100 automotive qualification and tape-and-reel packaging format. Ensure compatibility with 8-pin MSOP footprint requirements. Confirm that the 1.3A current rating aligns with the target LED string configuration. Validate that the 1MHz switching frequency fits the electromagnetic interference constraints of the final application environment.
Selection Notes
Select this component when designing for 12V or 24V automotive environments requiring high efficiency and compact PCB size. The integrated power switch reduces external component count compared to discrete solutions. Consider the 1MHz frequency for smaller passive components. Ensure the external resistor selection accurately targets the desired LED current within the 1.3A limit.
Part Context
This part belongs to the AL8807 series of adjustable buck LED drivers. It is functionally similar to the AL8807BMP-13 but includes automotive-grade qualification. The 'Q' suffix typically denotes AEC-Q100 compliance, while 'MP' indicates the MSOP package and reel packing. It serves as a robust solution for replacing multi-component discrete designs in automotive lighting.
Replacement Considerations
The AL8807BMP-13 is a non-automotive grade equivalent with identical pinout and electrical characteristics. Verify if automotive qualification is strictly required before substituting. Other parts in the AL8807 family may differ in switching frequency or package type.
