Overview
The MP6538GV-Z is a three-phase BLDC motor pre-driver from Monolithic Power Systems. It operates with a supply voltage of 8.5V to 14V and supports load voltages from 8V to 100V. The device features an integrated LDO, internal charging pump for high-side gate drive, and programmable overcurrent protection. It utilizes a 28-QFN (4x5) package with exposed pad and functions within a junction temperature range of -40°C to 125°C.
Feature Summary
- Integrates internal low-dropout regulator and charge pump for reliable high-side MOSFET driving
- Provides adjustable dead-time control to prevent shoot-through in half-bridge configurations
- Includes comprehensive protection mechanisms such as overcurrent protection, under-voltage lockout, and thermal shutdown
Applications
- Three-phase brushless DC motor drives
- Industrial automation systems
- Battery-powered equipment requiring low-power sleep modes
Procurement Notes
Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status according to manufacturer declarations. Confirm the 28-QFN package dimensions match the design footprint. Ensure the application voltage does not exceed the 100V rating. Check for moisture sensitivity level requirements during storage and handling.
Selection Notes
Select this component when designing three-phase BLDC applications requiring up to 100V operation. It is suitable for systems needing integrated gate drive support with external N-channel MOSFETs. Consider the 28-QFN package for compact surface-mount designs. Evaluate the need for programmable overcurrent protection and adjustable dead-time settings.
Part Context
This part belongs to the MP6538 series of motor drivers. It serves as a pre-driver for controlling external power MOSFETs in three-phase configurations. The series focuses on providing robust gate drive capabilities with integrated safety features for industrial and consumer motor control applications.
Replacement Considerations
MP6539GV-Z offers similar functionality with potentially different packaging or minor parameter variations. Verify pin compatibility and electrical specifications before substitution.
