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.).
