MP6539BGV-P

Overview

The MP6539BGV-P is a three-phase brushless DC motor pre-driver designed for high-voltage applications. It supports a supply voltage range of 8 V to 100 V and delivers up to 1 A output current per phase. The device features a low quiescent current of 700 uA and operates within a temperature range of -40°C to +125°C. Packaged in a QFN-28 surface-mount format, it integrates protection mechanisms including overcurrent protection, under-voltage lockout, and thermal shutdown.

Feature Summary

• Integrates internal charge pump to maintain high-side gate drive voltage during continuous high-level outputs
• Includes programmable overcurrent protection with external MOSFET threshold adjustment
• Features adjustable dead-time control to prevent shoot-through in half-bridge configurations
• Provides fault indication output for system monitoring and diagnostic purposes

Applications

• Three-phase BLDC motor drives in industrial automation systems
• Brushless fan controllers for server and networking equipment
• Electric vehicle auxiliary power unit motor control
• High-performance linear actuator positioning systems

Procurement Notes

Verify the specific suffix 'P' indicates cut-tape or reel packaging variants when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference pinout diagrams with PCB layout requirements to guarantee correct thermal pad connection and signal alignment.

Selection Notes

Select this component for designs requiring robust pre-driving capabilities for external N-channel MOSFETs up to 100 V. The integrated charge pump simplifies bootstrap circuit design compared to standard drivers. Consider the QFN-28 package for superior thermal dissipation in compact layouts. Evaluate the 1 A peak drive current against the total gate charge of the selected external power devices to ensure adequate switching speeds.

Part Context

This part belongs to the MP6539 series of motor drivers manufactured by Monolithic Power Systems. The series focuses on providing reliable pre-driver functionality for three-phase BLDC applications. The BGV-P designation specifies the TSSOP-28EP package variant with specific tape-and-reel or cut-tape distribution options available through authorized distributors.
