MPQ4487AGU-AEC1-P

Overview

The MPQ4487AGU-AEC1-P is a synchronous step-down switch-mode converter designed for automotive applications, qualified to AEC-Q100 standards. It operates with an input voltage range of 6 V to 40 V and delivers up to 6 A output current through a single regulated output channel. The device utilizes a QFN-26 package and supports a programmable switching frequency from 250 kHz to 2.2 MHz. Key electrical parameters include a maximum operating temperature of +125 C, a minimum of -40 C, and a shutdown feature for power management.

Feature Summary

• Supports dual USB charging ports with EN and fault indication capabilities
• Passed Apple MFI R33 certification test
• Passed USB-IF Type-C certification test

Applications

• Automotive infotainment systems
• Vehicle navigation units
• Digital instrument clusters

Procurement Notes

Verify the specific suffix 'P' indicates cut tape packaging versus 'Z' for reel configuration when sourcing. Confirm AEC-Q100 qualification status aligns with target automotive grade requirements. Check datasheet for thermal pad connection guidelines in QFN-26 layout. Ensure input voltage does not exceed 40 V maximum rating during operation.

Selection Notes

Select this component for designs requiring certified USB charging integration in automotive environments. Compare against MPQ4488 series if multiple outputs are needed. Consider the 6 A current limit for load requirements. Evaluate the wide input voltage range compatibility with vehicle battery systems.

Part Context

This part belongs to the MPS MPQ4487 series of high-efficiency buck converters. It is distinct from the MPQ4488 which offers three outputs. The device integrates control logic for USB protocols within a compact footprint suitable for space-constrained automotive PCB layouts.

Replacement Considerations

MPQ4487AGU-AEC1-Z is the reel version of the same functional device.
