What made you select the Qorvo ACT72350 as a featured product?
I’ve selected the ACT72350 from Qorvo for its impressive range of features. This standalone three-phase BLDC motor driver is a fantastic choice for applications that require high performance and flexibility. It can drive up to a 20S battery pack with a maximum of 160V, which makes it a great option for demanding motor control systems. What’s particularly exciting about the ACT72350 is its built-in Analog Front End (AFE) that powers the system MCU, while also offering strong drive capabilities. It’s a well-rounded solution, integrating all the necessary analog blocks for current measurement and protection, which helps streamline design and reduce the BOM.
The ACT72350 features Qorvo’s unique Configurable Power Manager (CPM), which enables efficient and flexible power management for a variety of power sources. This “all-in-one” solution features a high-voltage switching controller capable of operating a buck converter, as well as a configurable medium-voltage regulator and three linear-regulated voltage supplies. The device is controlled through tri-phase inverter PWM input signals, providing easy integration into existing systems. The CPM’s versatile capabilities ensure reliable power delivery across multiple power sources, making it ideal for complex motor control applications.
The device also boasts an impressive array of features aimed at simplifying design and reducing system complexity. Integrated bootstrap diodes, along with all the necessary analog blocks for current measurement and device protection, minimize the external components required, reducing your BOM. Additionally, the ACT72350 includes Qorvo’s patent-pending Multi-Mode Power Manager™, Configurable Analog Front End™, and Application Specific Power Drivers™, enhancing both system flexibility and performance. The robust braking feature adds an extra layer of safety, making the device suitable for critical applications where safety is paramount. Housed in a compact 57-pin, 9×9 mm TQFN package, the ACT72350 offers a streamlined solution for your motor control needs.
