MP6532GF-P

Overview

The MP6532GF-P is a three-phase brushless DC motor pre-driver from Monolithic Power Systems, designed for automotive and industrial applications. It operates within a supply voltage range of 5V to 60V and supports up to six external N-channel power MOSFETs arranged in three half-bridges. The device integrates a regulated charge pump and trickle-charge circuit to maintain high-side gate drive voltage even at 100% duty cycle. It features AEC-Q100 qualification, operates between -40°C and +125°C, and is housed in a 28-pin QFN-4x4mm package with exposed pad.

Feature Summary

• Integrates trickle-charge circuitry to sustain high-side gate drive voltage during continuous 100% duty cycle operation
• Supports direct interface with three Hall effect sensors for 120-degree commutation logic
• Includes programmable overcurrent protection, adjustable dead-time control, and fault indication output
• Features low-power sleep mode suitable for battery-supplied systems

Applications

• Automotive cooling fan and blower motor control systems
• Electric power steering actuators
• Industrial pump and valve motor drives
• Battery-operated portable equipment requiring efficient motor management

Procurement Notes

Verify the specific suffix GF-P corresponds to the QFN-28 (4x4mm) package variant when ordering. Confirm that the component meets AEC-Q100 Grade 1 requirements if used in harsh automotive environments. Ensure proper thermal design due to the exposed pad structure. Check for moisture sensitivity labeling prior to soldering. Validate compatibility with external MOSFET gate drive requirements against the official datasheet specifications.

Selection Notes

Select this pre-driver when designing systems requiring wide input voltage support up to 60V and precise control of external power stages. It is appropriate for applications needing integrated Hall sensor interfacing without external logic gates. Consider the QFN package for compact layouts requiring efficient heat dissipation through the thermal pad. Evaluate the need for trickle-charge functionality if operating near maximum duty cycles.

Part Context

The MP6532 series belongs to MPS's portfolio of BLDC motor pre-drivers, bridging microcontroller commands to high-power external switches. Unlike integrated drivers, this component relies on external MOSFETs for current handling, offering flexibility in power stage selection. It complements other MPS solutions like the MP6530 and MP6531 by providing enhanced high-side drive stability and automotive-grade reliability.

Replacement Considerations

The MP6532GR-P serves as a pin-compatible alternative in the TSSOP-28EP package. The MPQ6532GVE-AEC1-P is an equivalent automotive-qualified version with potential packaging differences. Verify pinout and thermal characteristics before substitution.
