MPQ6526GUE-AEC1-Z

Overview

The MPQ6526GUE-AEC1-Z is a Hex Half-Bridge Motor Driver with Serial Input Control, designed for automotive applications. It features six independent half-bridge outputs capable of delivering up to 900 mA output current per channel. The device operates within a supply voltage range of 7 V to 28 V and supports a switching frequency of 3 MHz. It is qualified under AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +150°C. Packaged in a QFN-24 surface-mount format, the component integrates power MOSFETs and control logic into a single monolithic structure.

Feature Summary

• Integrates six half-bridge drivers with serial input control interface
• AEC-Q100 Grade 1 qualified for automotive reliability requirements
• Supports high-temperature operation up to 150°C junction temperature
• Includes internal protection mechanisms against over-temperature and short circuits

Applications

• Automotive seat adjustment motor control
• Power window and sunroof actuator drivers
• HVAC blower motor control systems
• Fuel pump driver circuits
• General automotive solenoid and relay driving

Procurement Notes

Verify that the specific suffix 'AEC1' matches the required automotive qualification grade for your design. Confirm the package type is QFN-24 and ensure thermal management solutions are adequate for the expected power dissipation. Check RoHS compliance status as indicated in official documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring multiple independent low-current motor or load drives controlled via a serial interface. It is suitable for applications needing AEC-Q100 certification and wide operating temperature ranges. Consider the 900 mA per channel limit and 28 V maximum supply voltage to ensure compatibility with target loads and power rails.

Part Context

This part belongs to the MPQ6526 series of hex half-bridge drivers from Monolithic Power Systems. It is specifically engineered for automotive environments, offering integrated power stages and control logic. The series provides a compact solution for managing multiple actuators or loads in vehicle electronics, reducing board space compared to discrete implementations.

Replacement Considerations

MP6526GU-Z is a parameter-equivalent alternative within the same manufacturer's portfolio. Verify if the non-AEC variant meets the specific automotive reliability and temperature requirements of the application before substitution.
