MP6541GQKT-Z

Overview

The MP6541GQKT-Z is a three-phase power stage designed for brushless DC motor controllers. It integrates high-side and low-side drivers with PWM and enable inputs, supporting an operating supply voltage range of 4.75 V to 40 V. The device delivers an output current of 8 A per phase and operates at a switching frequency of 2 MHz. It features a TQFN-26 package (6x6 mm) suitable for surface mount installation. The component functions within a temperature range of -40°C to +125°C TJ, with a maximum power dissipation of 5.84 W.

Feature Summary

• Integrates three half-bridge outputs for direct BLDC motor drive
• Supports PWM control signals with dedicated enable functionality
• Includes internal gate drivers for high-side and low-side MOSFETs

Applications

• Brushless DC motor control systems
• Industrial motion control applications
• Automotive electronics requiring three-phase power stages

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status as defined by Monolithic Power Systems. Confirm that the TQFN-26 package dimensions match the target PCB footprint requirements. Ensure the 40 V maximum supply voltage aligns with the system's power rail specifications before finalizing procurement.

Selection Notes

Select this component when an integrated three-phase driver with 8 A capability is required. The 2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the TQFN-26 thermal performance if high continuous currents are expected in the application environment.
