MP6530GR-Z

Overview

The MP6530GR-Z is a three-phase brushless DC motor pre-driver designed for gate drive applications. It supports driving six N-channel power MOSFETs arranged in three half-bridges with a supply voltage range of 5V to 60V. The device features a quiescent current of 950 uA and an output current capability of 1 A per channel. It operates within a temperature range of -40°C to +125°C and utilizes a QFN-28 package.

Feature Summary

• Integrates trickle charge circuitry to maintain bootstrap gate drive voltage, enabling 100% duty cycle operation without external charging constraints.
• Provides programmable overcurrent protection and adjustable dead-time control to prevent shoot-through conditions in the half-bridge outputs.
• Includes comprehensive safety mechanisms such as undervoltage lockout (UVLO) and thermal shutdown to ensure reliable system protection.

Applications

• Brushless DC motor drives
• Fan motor controllers
• Industrial automation systems

Procurement Notes

Verify the specific suffix GR-Z against the manufacturer's official datasheet to confirm the exact package variant and RoHS compliance status. Ensure that the ordering quantity aligns with the standard factory reel size requirements specified by Monolithic Power Systems. Cross-reference the part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when designing three-phase BLDC motor applications requiring a dedicated pre-driver stage rather than an integrated power stage. The wide input voltage range accommodates various bus voltages up to 60V. Consider the thermal performance of the QFN-28 package relative to the expected power dissipation and ambient operating conditions during the design phase.

Part Context

This component belongs to the MP6530 family of pre-drivers from Monolithic Power Systems. The family includes variants such as MP6530GF-P and MP6530GR-P, which share similar functional characteristics but may differ in packaging or specific manufacturing lot attributes. The MP6530 series is categorized under motor drivers and motion controllers within the PMIC portfolio.

Replacement Considerations

MP6530GR-P is listed as a substitute part number by the manufacturer. Verify pin compatibility and electrical specifications before substitution.
