MP6541GQKT-P

Overview

The MP6541GQKT-P is a three-phase power stage designed for brushless DC motor control applications. It integrates high-side and low-side drivers capable of delivering an output current of 8 A. The device operates within a supply voltage range of 4.75 V to 40 V, with a maximum rating of 45 V. It supports a switching frequency of 2 MHz and functions across an extended temperature range from -40°C to +125°C. The component features PWM and enable inputs, consumes 4 mA of quiescent current, and dissipates up to 5.84 W of power. It is housed in a TQFN-26 surface-mount package.

Feature Summary

• Integrates three-phase power stage with dedicated high-side and low-side drivers for BLDC motor control
• Supports PWM modulation and hardware enable inputs for precise operational control
• Operates at a fixed 2 MHz switching frequency to minimize external passive component size

Applications

• Brushless DC (BLDC) motor drives
• Industrial motion control systems
• Automotive ignition controllers

Procurement Notes

Verify the specific suffix 'P' corresponds to the standard reel packaging configuration as listed in official Monolithic Power Systems documentation. Confirm that the TQFN-26 package variant matches your PCB footprint requirements. Ensure the 40 V continuous supply voltage aligns with your system's rail specifications. Cross-reference the 8 A output current capability against your thermal management design constraints.

Selection Notes

Select this component when designing three-phase BLDC motor applications requiring high current drive in a compact form factor. The 2 MHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Verify compatibility with your microcontroller's PWM signal levels. Consider the TQFN-26 package for its thermal performance relative to the 5.84 W power dissipation rating under expected load conditions.

Part Context

This part belongs to the MP6541 family of three-phase power stages manufactured by Monolithic Power Systems. It is categorized under Motor / Motion / Ignition Controllers & Drivers within the PMIC segment. The device serves as a complete power stage solution, eliminating the need for discrete MOSFETs and gate drivers in standard BLDC motor implementations.

Replacement Considerations

The MP6541GQKTE-AEC1-P is an automotive-grade qualified version of this component. Verify if AEC-Q100 certification is required for your application before substituting.
