MPQ6519GR-AEC1-P

Current Regulation/Management Overview

The MPQ6519GR-AEC1-P is an automotive-grade half-bridge current regulator manufactured by Monolithic Power Systems. It operates within a supply voltage range of 3V to 28V and delivers a continuous output current of 5A. The device features a low quiescent current of 370uA and supports switching frequencies from 30kHz to 300kHz. It is housed in a QFN-19 package, rated for operation between -40°C and +125°C, and holds AEC-Q100 qualification.

Current Regulation/Management Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Integrated high-side and low-side current sensing capabilities
• Adjustable switching frequency for optimized efficiency
• Low quiescent current for improved power management

Current Regulation/Management Applications

• Automotive fan motor control
• Solenoid driver circuits
• Injector control systems
• General automotive motion control applications

Current Regulation/Management Procurement Notes

Verify the specific suffix 'P' indicates the standard reel packaging configuration as documented by the manufacturer. Confirm that the component meets the required AEC-Q100 grade specifications for your target automotive application. Ensure compatibility with the QFN-19 footprint during PCB layout review. Cross-reference the datasheet for any updates regarding thermal performance or pinout definitions before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when a robust, automotive-certified half-bridge solution is required for driving inductive loads such as fans or solenoids. The 5A current rating suits moderate-power applications where precise current regulation is necessary. Consider the 3V to 28V input range for direct battery connection scenarios. Evaluate the thermal dissipation requirements based on the QFN-19 package size and expected operating temperatures.

Current Regulation/Management Part Context

This part belongs to the MP6519 series of motor controllers and drivers designed specifically for automotive environments. It serves as a specialized integrated circuit for managing high-current loads in vehicle systems. The series focuses on providing reliable current regulation with built-in protection features suitable for harsh automotive electrical conditions.

Current Regulation/Management Replacement Considerations

The MP6519GQ-P is a non-automotive variant within the same product family offering similar electrical characteristics but without AEC-Q100 certification. Verify if the automotive qualification is strictly required for your application before considering substitution.
