MPQ6531

5V to 60V, Three-Phase Brushless

DC Motor Pre-Driver

AEC-Q100 Qualified

FEATURES

DESCRIPTION



Wide 5V to 60V Input Voltage Range

Charge Pump Gate Drive Supply

Bootstrap High-Side Driver with Trickle-

Charge Circuit Supports 100% Duty Cycle

Operation

The MPQ6531 is a gate driver IC designed for

three-phase brushless DC motor driver

applications. It is capable of driving three half-

bridges consisting of six N-channel power

MOSFETs up to 60V.



Low-Power Sleep Mode

Programmable Short-Circuit Protection

Over-Current Protection

Adjustable Dead-Time Control to Prevent

Shoot-Through

The MPQ6531 integrates a regulated charge

pump to generate gate drive power, and uses a

bootstrap capacitor to generate a supply

voltage for the high-side MOSFET driver. An

internal trickle-charge circuit maintains

sufficient high-side gate driver voltage at 100%

duty cycle.



Thermal Shutdown and UVLO Protection

Fault Indication Output

Thermally Enhanced Surface-Mounted

Package

Internal safety features include programmable

short-circuit protection, over-current protection,

adjustable dead-time control, under-voltage

lockout, and thermal shutdown.



Available in AEC-Q100 Grade 1

APPLICATIONS



Three-Phase Brushless DC Motors

Permanent Magnet Synchronous Motors

Automotive Actuators, Pumps, and Fans

The MPQ6531 is available in a 4mmx5mm

QFN-28 package with an exposed thermal pad.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For

MPS green status, please visit the MPS website under Quality Assurance.
