MP6543HGL-A-P

Overview

The MP6543HGL-A-P is a three-phase power stage designed for brushless DC motor applications. It operates within a supply voltage range of 3 V to 22 V and delivers an output current of 2 A. The device features separate high-side and low-side inputs, allowing for flexible control integration. It supports PWM interface signals and includes built-in protection mechanisms such as over-current and over-temperature protection. The component is housed in a 24-QFN (3x4) package with exposed pad for thermal performance. It functions as a half-bridge driver configuration suitable for motion control systems.

Feature Summary

• Integrates three half-bridges with separate high-side and low-side inputs for precise control
• Includes integrated bidirectional current-sense amplifiers for feedback monitoring
• Features built-in over-current and over-temperature protection with fault indication

Applications

• Three-phase Brushless DC Motor drives
• Drone propulsion systems
• Robotics actuation modules

Procurement Notes

Verify availability status carefully as this specific suffix variant may be subject to limited supply or discontinuation notices. Confirm the exact ordering part number against the manufacturer's latest datasheet to ensure compatibility with design requirements. Check for alternative suffixes if stock is unavailable. Validate RoHS compliance documentation prior to procurement.

Selection Notes

Select this component when a dedicated three-phase power stage with separate input controls is required. It is suitable for designs needing integrated current sensing and protection without external discrete components. Consider the 24-QFN package constraints for thermal management. Ensure the host controller can provide the necessary PWM and enable signals for the separate high-side and low-side inputs.

Part Context

This part belongs to the MP6543 family of motor drivers from Monolithic Power Systems. It serves as a power stage solution for BLDC motors, complementing external microcontrollers that handle commutation logic. The 'A' suffix typically denotes specific manufacturing lot or revision details, while 'P' indicates tape and reel packaging. It is distinct from variants with different input configurations or package types.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include MP6543HGL-B-P and MP6543HGL-B-Z. These alternatives offer similar electrical specifications and pinout compatibility. Verify functional equivalence regarding input signal handling and protection thresholds before substitution.
