MP6539GV-P

Overview

The MP6539GV-P is a three-phase BLDC motor pre-driver manufactured by Monolithic Power Systems. It operates within an 8V to 100V supply range and delivers a 1A output current per phase. The device features a low quiescent current of 700uA and supports non-inverting logic inputs with thresholds of 0.8V and 2V. It utilizes a half-bridge configuration with six N-channel MOSFET drivers, housed in a 28-VFQFN package. The component functions across a temperature range of -40°C to +125°C TJ.

Feature Summary

• Provides dedicated gate driving for three-phase brushless DC motors using a half-bridge topology.
• Supports high-voltage operation up to 100V with integrated bootstrap capability.
• Features low power consumption with a specified operating supply current of 700uA.
• Includes thermal protection mechanisms to ensure reliable operation under varying load conditions.

Applications

• Three-phase brushless DC motor control systems
• Industrial motion control applications
• Automotive ignition and actuator drivers

Procurement Notes

Verify the specific suffix GV-P against official MPS documentation to confirm the QFN-28 package and tape-and-reel quantity. Ensure compatibility with system voltage requirements not exceeding 100V. Confirm that the non-inverting input logic levels align with the host controller's output specifications before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring a dedicated pre-driver for three-phase BLDC motors rather than an integrated full bridge. Consider the 1A peak current capability and the 28-VFQFN footprint constraints. Evaluate the need for external bootstrap diodes and capacitors based on the switching frequency and duty cycle requirements of the target application.

Part Context

The MP6539 belongs to the MPS MP6539 series of motor controllers and drivers. It serves as a specialized interface between low-voltage logic controllers and high-voltage motor phases. Unlike integrated driver ICs, it focuses on providing robust gate drive signals for external or internal power stages, offering flexibility in power stage design.
