Overview
The MPQ4425BGQB-AEC1-P is an automotive-grade, high-efficiency synchronous step-down LED driver IC manufactured by Monolithic Power Systems. It features a buck topology with a single output channel capable of delivering up to 1.5 A of continuous output current. The device operates within an input voltage range of 4 V to 36 V and supports a fixed switching frequency of 2.2 MHz. It is qualified under the AEC-Q100 standard for automotive applications and is housed in a QFN-13 package designed for surface-mount installation.
Feature Summary
- High-efficiency synchronous buck architecture optimized for automotive LED lighting applications
- Integrated PWM dimming capability for precise brightness control
- Built-in short circuit and thermal protection mechanisms for enhanced system reliability
Applications
- Automotive exterior LED lighting systems
- Automotive interior ambient LED illumination
- General-purpose automotive LED driver circuits
Procurement Notes
Verify the specific suffix 'P' indicates the tape-and-reel packaging configuration as documented by the manufacturer. Confirm that the AEC-Q100 qualification aligns with your vehicle's component acceptance criteria. Ensure the QFN-13 wettable flank package requirements are compatible with your assembly process capabilities. Cross-reference the 2.2 MHz switching frequency against your electromagnetic interference constraints.
Selection Notes
Select this component when designing automotive LED drivers requiring a 1.5 A output capacity and a 36 V maximum input voltage. The 2.2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. The AEC-Q100 qualification ensures suitability for harsh automotive environments. Consider the QFN-13 package size relative to available PCB real estate and thermal dissipation needs.
Part Context
This part belongs to the MPQ4425 family of synchronous step-down LED drivers from Monolithic Power Systems. The family includes variants with different switching frequencies and package options, such as the 400 kHz versions or TSOT-23-8 packages. The BGQB suffix specifically denotes the 2.2 MHz frequency variant in the automotive-grade QFN-13 form factor.
Replacement Considerations
Direct substitutes include other MPQ4425 variants like MPQ4425AGQB-P or MPQ4425CGQBE-AEC1-Z, provided the switching frequency and package type match the design requirements. Verify pinout compatibility before substitution.
