MPQ6533GUE-AEC1-Z

Overview

The MPQ6533GUE-AEC1-Z is a three-channel automotive pre-driver designed for brushless DC and brushed DC motors. It operates within a supply voltage range of 6V to 40V and supports up to 1A output current per channel. The device features an SPI interface for configuration, including adjustable slew rate, dead time, and overcurrent protection thresholds. It integrates an internal LDO and charge pump, enabling 100% duty cycle operation. The component is housed in a 32-QFN (5mm x 5mm) package and is qualified to AEC-Q100 standards, with a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates internal LDO and charge pump to support 100% duty cycle operation for efficient motor driving.
• Features configurable SPI interface allowing adjustment of slew rate, dead time, and overcurrent protection thresholds.
• Includes comprehensive fault diagnosis capabilities such as load open/short detection, overtemperature protection, and reverse battery protection.

Applications

• Electric tailgate actuators
• Electric sunroof mechanisms
• Electric seat adjustment systems

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and lead-free status as per manufacturer declarations. Confirm the package type matches the design requirements, specifically the 32-QFN (5x5mm) footprint. Ensure the application environment stays within the specified -40°C to 150°C junction temperature range. Check for AEC-Q100 qualification documentation if automotive reliability certification is required for the final product assembly.

Selection Notes

Select this component when a three-channel driver is needed for BLDC or dual brushed DC motors in automotive environments. The integrated charge pump eliminates the need for external bootstrap circuits, simplifying board layout. Consider the SPI configurability for optimizing EMI through adjustable slew rates and dead times. Ensure the input voltage range of 6V to 40V aligns with the vehicle's power system specifications.

Part Context

This part belongs to the MPQ6533 series from Monolithic Power Systems, specifically tailored for automotive applications. It is distinct from other MPS motor drivers by its specific integration of LDO and charge pump for high-duty-cycle performance. The AEC1 suffix denotes automotive-grade qualification, differentiating it from standard industrial variants.

Replacement Considerations
