MP6531A

5V to 60V, Three-Phase, Brushless, DC Motor Pre-Driver with Separate HS/LS Control

Datasheet

Description

The MP6531A is a gate driver IC designed for three-phase, brushless, DC motor driver applications. The MP6531A is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 60V. The MP6531A uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal trickle-charge circuit maintains a sufficient gate driver voltage at 100% duty cycle. Internal safety features include programmable over-current protection (OCP), adjustable dead-time control, under-voltage lockout (UVLO), and thermal shutdown. The MP6531A is available in 28-pin TSSOP-EP (9.7mmx6.4mm) and QFN-28 (4mmx4mm) packages with exposed thermal pads on the back.

Evaluation Tools

EVQ6531-V-00A Evaluation Kit 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 three half-bridges consisting of six 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 (e.g. MCU, FPGA, etc.).
