MPQ6524GRE-AEC1-Z

Overview

The MPQ6524GRE-AEC1-Z is a quad half-bridge motor driver with serial input control, designed for automotive applications. It is qualified to AEC-Q100 standards and operates within an extended temperature range of -40°C to +125°C. The device integrates four independent half-bridges capable of driving inductive loads such as DC motors, solenoids, or lamps. It features low on-resistance switches to minimize power dissipation and includes comprehensive protection mechanisms against over-current, under-voltage lockout, and thermal overload.

Feature Summary

• Integrates four independent half-bridge drivers for simultaneous control of multiple loads
• Supports serial interface communication for simplified control logic integration
• Includes built-in protection against short circuits, over-temperature, and undervoltage conditions

Applications

• Automotive seat adjustment actuators
• Vehicle window and sunroof lift motors
• HVAC system fan and blower control
• Power tailgate and trunk latch mechanisms

Procurement Notes

Verify the specific suffix Z indicates tape-and-reel packaging configuration. Confirm AEC-Q100 grade compliance matches project requirements. Check RoHS status for environmental regulations. Ensure serial interface voltage levels align with the host microcontroller. Validate operating temperature range suitability for the intended enclosure environment.

Selection Notes

Select this component when four-channel motor control is required in a compact footprint. Consider the serial interface capability if GPIO pin conservation is critical. Evaluate the thermal performance relative to the expected load current and ambient conditions. Compare against triple-bridge alternatives if one channel remains unused to optimize cost and board space.

Part Context

This part belongs to the MPS automotive-grade motor driver family, specifically engineered for high-reliability vehicle systems. The GRE package denotes a thermally enhanced QFN variant suitable for surface-mount assembly. It complements other MPS PMIC solutions by providing dedicated actuation control alongside power management functions in modern automotive architectures.

Replacement Considerations

MPQ6523GRE-AEC1-P serves as a triple-bridge alternative within the same series. Verify pin compatibility and control interface differences before substitution. Assess thermal performance changes due to the reduced channel count.
