MPQ6628GF-AEC1-P

Overview

The MPQ6628GF-AEC1-P is an automotive-grade octal half-bridge motor driver manufactured by Monolithic Power Systems. It supports a supply voltage range of 5.5 V to 40 V and delivers an output current of 800 mA per channel. The device features serial input control via SPI interface and operates within a temperature range of -40°C to +150°C. It is housed in a TSSOP-28 EP package and holds AEC-Q100 qualification for automotive reliability.

Feature Summary

• Octal half-bridge configuration providing eight independent output channels for complex motor control applications
• Integrated serial peripheral interface (SPI) for simplified digital control and status monitoring
• Automotive qualification ensuring compliance with AEC-Q100 standards for high reliability
• Extended thermal performance capability supporting operation up to 150°C junction temperature

Applications

• Automotive seat actuator systems requiring multi-channel drive capabilities
• Vehicle door lock and latch mechanisms utilizing multiple motors
• Power window and sunroof control modules
• HVAC blower motor and vent flap actuators

Procurement Notes

Verify the specific suffix 'AEC1' confirms automotive grade qualification and 'P' indicates tape and reel packaging when sourcing. Confirm the manufacturer is Monolithic Power Systems Inc. to ensure component authenticity. Check datasheet revisions for any pinout or electrical parameter updates prior to final design integration.

Selection Notes

Select this component for designs requiring multiple low-current motor outputs from a single integrated circuit. The 800 mA rating suits small actuators rather than high-power loads. Ensure the system voltage remains within the 5.5 V to 40 V operating window. The TSSOP-28 EP package requires adequate thermal management on the PCB ground plane to handle power dissipation effectively.

Part Context

This part belongs to the MPQ6628 family of motor drivers designed specifically for automotive environments. It integrates both logic and power stages, reducing external component count compared to discrete solutions. The series focuses on providing robust control for various electromechanical actuators found in modern vehicle architectures.

Replacement Considerations

MPQ6628GF-AEC1-Z is a verified alternative variant within the same product line offering identical functionality.
