MP6539GV-Z

Overview

The MP6539GV-Z is a three-phase BLDC motor pre-driver manufactured by Monolithic Power Systems. It operates with a supply voltage range of 8.5 V to 14 V and supports load voltages up to 100 V. The device features three half-bridge outputs capable of delivering 1 A output current, with a typical quiescent current of 700 uA. It utilizes a 28-QFN (4x5 mm) surface-mount package and functions within an operating temperature range of -40°C to +125°C TJ.

Feature Summary

• Provides three half-bridge pre-driver outputs for external MOSFET control in three-phase brushless DC motor applications.
• Supports high-voltage operation with a maximum load voltage rating of 100 V.
• Integrates low quiescent current consumption to enhance system efficiency during standby or idle states.

Applications

• Three-phase Brushless DC (BLDC) motor control systems
• Industrial motion control drives
• Automotive electronic components requiring robust pre-driver stages

Procurement Notes

Verify the specific suffix 'GV' confirms the QFN-28 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management design accounts for the specified junction temperature limits during operation.

Selection Notes

Select this component for designs requiring a dedicated pre-driver stage rather than an integrated power driver. Verify that the external MOSFET selection aligns with the 100 V load voltage capability and the 1 A drive current requirements. Ensure the control logic interface matches the non-inverting input specifications provided in the datasheet.

Part Context

This part belongs to the MP6539 series of motor controllers and drivers from Monolithic Power Systems. It serves as a pre-driver solution, distinct from fully integrated gate drivers, allowing designers to select external power switches tailored to specific current and voltage needs.

Replacement Considerations

MP6539CGV-Z: Offers similar functionality but rated for 80 V load voltage instead of 100 V. MP6539BGV-P: Alternative package option within the same series. Verify pinout compatibility and voltage ratings before substitution.

FAQ

Is the MP6539GV-Z an integrated motor driver or a pre-driver?
