MP6543HGL-Z

Overview

The MP6543HGL-Z is a three-phase power stage designed for brushless DC motor applications. It integrates three half-bridge drivers with NMOS technology, supporting a supply voltage range of 3V to 22V and delivering an output current of 2A per phase. The device accepts PWM inputs for each H-bridge and features dedicated enable controls. Packaged in a 24-QFN (3x4) surface-mount format, it operates within a junction temperature range of -40°C to 125°C.

Feature Summary

• Integrates three half-bridge drivers with NMOS technology for efficient power switching
• Accepts independent PWM and enable inputs for each high-side bridge
• Provides full integration of control logic and power stages in a compact package

Applications

• Brushless DC (BLDC) motor drives
• Multi-phase motor control systems
• Motion control applications requiring integrated power stages

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's latest documentation to confirm compliance with RoHS3 standards and lead time requirements. Ensure that the 24-QFN package dimensions match the target PCB footprint. Confirm that the 2A continuous current rating aligns with the thermal management design of the final application.

Selection Notes

Select this component when a fully integrated three-phase driver is required without external gate drivers. The MP6543HGL-Z is suitable for designs needing independent PWM control per phase. Compare against variants like the MP6543HGL-B-Z if different input configurations or updated manufacturing revisions are preferred. Ensure the 22V maximum supply voltage meets system constraints.

Part Context

This part belongs to the MP6543 family of three-phase power stages from Monolithic Power Systems. It serves as a complete solution for driving BLDC motors by combining logic and power components. The 'HGL' designation indicates specific packaging and performance characteristics within the series, distinct from older versions like the MP6543CGL-Z which has lower current ratings.

Replacement Considerations

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