MP6537GV-P

Overview

The MP6537GV-P is a three-phase BLDC motor pre-driver from Monolithic Power Systems, designed for high-voltage applications up to 100 V. It features a supply voltage range of 8 V to 100 V and delivers a peak output current of 1 A per phase. The device operates within an extended temperature range of -40°C to +125°C and consumes a typical quiescent current of 700 µA. Packaged in a QFN-28 surface-mount format, it supports power dissipation up to 3.1 W and includes an integrated 12 V regulator.

Feature Summary

• Provides gate drive signals for external high-voltage MOSFETs in three-phase brushless DC motor configurations
• Integrates a dedicated linear regulator to supply internal logic and driver stages
• Supports wide input voltage operation suitable for industrial and automotive power systems

Applications

• Industrial automation motor control systems
• Automotive electronic cooling fans and pumps
• High-voltage brushless DC motor drives

Procurement Notes

Verify the specific suffix 'P' indicates cut-tape packaging availability against the required reel quantity. Confirm the QFN-28 thermal pad soldering requirements with the manufacturer's assembly guidelines. Ensure the application voltage does not exceed the 100 V absolute maximum rating. Check for moisture sensitivity level compliance during storage and reflow processes.

Selection Notes

Select this component when a dedicated pre-driver is required for external high-side and low-side MOSFETs rather than an integrated power stage. Consider the 1 A output capability for moderate load currents. Evaluate the 700 µA quiescent current for standby power constraints. Compare the QFN-28 package against alternative pinouts if board space is limited.

Part Context

This part belongs to the MP6537 series of BLDC motor pre-drivers. It complements other MPS solutions like the MP6539 and MPQ6532 by offering a 100 V rating. It serves as a control interface between microcontrollers and power switches, distinct from integrated drivers like the MP6637 which include internal MOSFETs.

Replacement Considerations

The MP6537GV-Z is a verified substitute variant within the same series, differing primarily in packaging configuration.
