3-Phase Brushless DC Motor Driver Using TC78B043FNG and TPD4204F

In recent years, for 3-phase brushless DC motors used in home appliances and industrial equipment such as air conditioners and air purifiers, there is an increasing trend toward adopting Interior Permanent Magnet (IPM) motors instead of Surface Permanent Magnet (SPM) motors to achieve lower cost, higher output, and higher torque. However, IPM motors tend to generate noise, creating a demand for motor controllers capable of low-noise and highly efficient control.
To address these needs, we provide a 3‑phase brushless DC motor driver application circuit capable of realizing both low noise and high efficiency. The provided materials include explanations of key design points for each circuit block, usage guidelines, adjustment methods, as well as schematic diagrams and PCB layout design information, which can help support and accelerate your motor control designs.
