Application Note for MPQ6531-AEC1 3-Phase Brushless DC Motor Pre-Driver

Overview

This application note provides technical guidance for the MPQ6531-AEC1, an automotive-grade three-phase brushless DC (BLDC) motor pre-driver. The device is designed to drive three half-bridges consisting of six N-channel power MOSFETs from a voltage supply up to 60V. The document covers design considerations for gate drive performance, integrated LDO usage, and the implementation of protection features such as over-current protection (OCP), under-voltage lockout (UVLO), and thermal shutdown for high-reliability automotive systems.
