MP6543HGL-B-P

Overview

The MP6543HGL-B-P is a three-phase power stage designed for brushless DC motor applications. It features an integrated half-bridge output configuration with a continuous output current of 2 A. The device operates within a supply voltage range of 3 V to 22 V and maintains a low operating supply current of 2.5 mA. It supports an extended junction temperature range from -40°C to +125°C. The component utilizes a surface-mount 24-QFN (3x4) package with exposed pad for thermal management.

Feature Summary

• Integrates three half-bridges with six N-channel power MOSFETs for direct motor drive
• Includes built-in 3.3V, 100mA LDO regulator for internal logic power
• Features integrated bidirectional current-sense amplifiers for precise control
• Supports 100% duty cycle operation with EN/PWM logic inputs

Applications

• Three-phase Brushless DC Motors
• Permanent Magnet Synchronous Motors
• Drones
• Robotics

Procurement Notes

Verify the specific suffix 'B' against official MPS documentation, as it may indicate a distinct binning or revision compared to standard variants like MP6543HGL-Z. Confirm availability status through authorized distributors, as supply constraints may apply. Ensure the selected packaging matches the required reel or cut-tape specifications for the manufacturing process.

Selection Notes

Select this component when a compact solution for three-phase BLDC motors is required with integrated power stages. The wide input voltage range accommodates various battery configurations. Consider the 2A current limit and thermal performance in the 24-QFN package for the specific application load requirements.

Part Context

This part belongs to the MP6543 family of motor drivers from Monolithic Power Systems. It serves as a dedicated power stage that interfaces with external controllers such as MCUs or FPGAs. The design simplifies system architecture by integrating high-side and low-side drivers into a single package.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include MP6543HGL-B-Z and MP6543HGL-A-P. Verify pin compatibility and electrical specifications before substitution.
