5V to 60V, Three-Phase Brushless DC Motor Pre-Driver AEC-Q100 Qualified



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.

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 a sufficient high-side gate driver voltage at 100% duty cycle.

Internal safety features include programmable short-circuit protection, over-current protection, adjustable dead-time control, under-voltage lockout, and thermal shutdown.

The MPQ6531 is available in a 4mmx5mm QFN-28 package with an exposed thermal pad.

5V to 60V, Three-Phase Brushless DC Motor Pre-Driver Evaluation Board

The EVQ6531-V-00A is an evaluation board for the MPQ6531, a three-phase BLDC motor pre-driver.

It operates from a supply voltage of up to 60V. It is configured to drive 3 half bridges consisting of 6 N-channel Power MOSFETs. The rotor position information is provided by the Hall sensors assembled in the motor and the driving control signals are generated by the external controller, such as MCU, FPGA, etc.
