MP6539BGV-Z

Overview

The MP6539BGV-Z is a three-phase BLDC motor pre-driver manufactured by Monolithic Power Systems. It operates with a supply voltage range of 8 V to 100 V and supports a logic supply of 8.5 V to 14 V. The device features three half-bridge outputs with a peak output current of 1 A (source) and 800 mA (sink). It utilizes a 28-VFQFN package with an exposed pad, designed for surface mount installation. The component functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Provides three-channel half-bridge pre-driver outputs for external power MOSFET control
• Supports high-voltage load operations up to 100 V
• Integrates non-inverting input logic for straightforward PWM interface compatibility

Applications

• Three-phase brushless DC motor control systems
• Industrial motion control applications
• Automotive electronic components requiring robust pre-driving capabilities

Procurement Notes

Verify the specific suffix 'GV-Z' against official Monolithic Power Systems documentation to confirm the QFN-28 package variant and lead-free compliance status. Ensure that the design accommodates the required thermal dissipation for the exposed pad configuration. Cross-reference the datasheet for any updates regarding moisture sensitivity levels or recommended soldering profiles prior to final procurement decisions.

Selection Notes

Select this component when designing circuits requiring a dedicated pre-driver for external high-voltage MOSFETs rather than an integrated power stage. The 100 V rating distinguishes it from lower-voltage variants like the MP6539CGV-Z. Consider the 28-pin footprint constraints and ensure adequate PCB space for the associated gate drive circuitry and heat management solutions suitable for the specified operating temperature range.

Part Context

This part belongs to the MP6539 series of motor drivers from Monolithic Power Systems. It serves as a specialized pre-driver solution, distinct from fully integrated drivers like the MP6537 or MP6538 which include internal power stages. The series focuses on providing flexible gate driving signals for external power switches in demanding motor control environments.

Replacement Considerations

MP6539BGV-P is listed as a direct substitute offering alternative packaging options such as cut tape.
