Overview
The MPQ4253BGU-AEC1-Z is a 36V synchronous step-down converter designed for automotive applications. It integrates a buck converter with two USB current-limit switches and charging port controllers, supporting one Type-A and one Type-C dual USB charging interface. The device operates within an input voltage range of 6V to 36V, delivering up to 5A output current. It features adjustable switching frequencies from 250kHz to 1MHz and maintains low quiescent current. Qualified under AEC-Q100 standards, it functions reliably across temperatures from -40°C to +125°C in a compact QFN-26 package.
Feature Summary
- Integrates monolithic step-down converter with dual USB current-limit switches
- Supports Type-A and Type-C dual USB charging protocols
- Automotive-grade reliability with AEC-Q100 qualification
- Wide input voltage range suitable for 12V and 24V automotive systems
Applications
- Automotive infotainment system power distribution
- Dual-port USB charging stations for vehicles
- In-dash navigation and display power supplies
- Aftermarket automotive audio and video equipment
Procurement Notes
Verify the specific suffix 'Z' indicates lead-free RoHS compliance as per manufacturer specifications. Confirm the 'GU' package code corresponds to the required QFN-26 footprint dimensions for PCB layout compatibility. Ensure the AEC-Q100 grade matches your vehicle's thermal and reliability requirements. Cross-reference the datasheet revision date to confirm pinout consistency with existing designs.
Selection Notes
Select this component when dual USB charging capability is required alongside efficient voltage regulation in space-constrained automotive environments. The integrated USB controllers simplify design by reducing external component count compared to discrete solutions. Consider the 5A output capacity against peak load demands of connected devices. Evaluate the fixed vs. adjustable frequency options if EMI constraints dictate specific switching ranges.
Part Context
This part belongs to the MPS MPQ4253 family of automotive-grade power management ICs. It complements other single-output buck converters like the MPQ4253AGU-AEC1-Z but adds specialized USB charging logic. The series targets modern vehicle interiors requiring multiple high-current USB ports without complex external controller architectures.
Replacement Considerations
The MPQ4253AGU-AEC1-Z is a related variant within the same family; verify if its specific USB support configuration meets your dual-port requirements. No direct cross-manufacturer substitutes are publicly confirmed for this integrated USB-buck combination.
