25 Qorvo 2021 Conclusion Brushless DC motors have become a popular choice in a wide range of consumer and industrial appliances. As brushless motors are incorporated into a broader range of applications, the ability to quickly design, prototype, and test motor controllers are keys to speeding the overall product design process. As a result, design engineers need a device that integrates all the required analog, power management, and gate-drive signal sources within a single package. The highly integrated Qorvo PAC5556 Power Application Controller meets the need for a compact power-control solution that reduces energy consumption, bulk, and noise in consumer and industrial motor applications. This design also meets tighter board space requirements and keeps the BOM cost to a minimum. Figure 2: The image provides a simplified diagram of a Qorvo PAC5556 used to control a BLDC motor.
