MP6539BGF-P

Overview

The MP6539BGF-P is a three-phase BLDC motor pre-driver from Monolithic Power Systems, designed for driving six 100V N-channel power MOSFETs in three half-bridge configurations. It operates within an 8.5V to 14V supply range and supports peak output currents of 800mA (sink) and 1A (source). The device features integrated current sampling amplifiers, programmable overcurrent protection, adjustable dead-time control, under-voltage lockout, and thermal shutdown. It utilizes bootstrap capacitors for high-side drive, supplemented by an internal charge pump for sustained high-level outputs. The component is housed in a TSSOP-28EP package with exposed pad.

Feature Summary

• Integrated current sampling amplifiers facilitate external MOSFET overcurrent protection
• Adjustable dead-time control prevents shoot-through between upper and lower bridge arms
• Internal charge pump maintains high-side gate voltage during continuous high-level output

Applications

• Three-phase brushless DC motor driver systems
• Industrial motion control applications
• Battery-powered equipment requiring low-power sleep modes

Procurement Notes

Verify the specific suffix against official MPS documentation, as standard part numbers may vary by packaging or tape-and-reel specifications. Confirm that the BGF designation corresponds to the TSSOP-28EP package type required for your design. Ensure compatibility with the intended PCB footprint and thermal management strategy before finalizing procurement orders.

Selection Notes

Select this component when designing three-phase BLDC drivers requiring 100V capability and integrated fault protection. It is suitable for applications needing adjustable dead-time and current sensing. Consider the TSSOP-28EP package constraints and verify that the 8.5V to 14V logic supply range aligns with the system's control interface voltages.

Part Context

The MP6539 belongs to the MPS MP6539 series of motor controllers and drivers. This family includes variants such as MP6539GV-P and MP6539GF-Z, which share similar electrical characteristics but differ in package types like QFN-28 or TSSOP-28EP. The series is categorized under Brushless DC Motor Controllers and Half Bridge drivers.

Replacement Considerations

MP6539GF-Z: Alternative variant in TSSOP-28EP package. MP6539GV-P: Alternative variant in QFN-28 package. MP6539CGV-P: Lower voltage version rated for 80V operation.
