3-Phase Gate Driver For BLDC Motor Control

The 160V motor driver helps build BLDC systems, uses fewer parts, works with many voltages, and fits battery devices like tools, bikes, and drones.

Qorvo, a global provider of connectivity and power solutions, has released the ACT72350—a 160V, 3-phase gate driver that simplifies BLDC motor control designs for automotive and industrial applications. This highly integrated device reduces solution size, slashes design time, and cuts BOM cost and component count compared to traditional discrete approaches.

The 3-phase gate driver is for engineers and manufacturers building BLDC motor control systems in automotive, industrial, and consumer applications. It can be used in electric vehicles, e-bikes, power tools, drones, and battery-powered equipment. With a 25V to 160V input range, an integrated analog front end, built-in power management, and support for various MCUs, the ACT72350 helps designers and developers reduce design effort, lower BOM cost, and shorten time-to-market.

The 3-phase gate driver can replace up to 40 discrete components in a motor control system. It features a configurable analog front end (AFE) for precise sensing and position detection, along with a built-in power manager that includes a DC-DC Buck converter and LDOs to support internal and external components, including the host MCU. With a wide input range of 25V to 160V, it supports a range of battery-powered applications.

Built on SOI technology, the 3-phase gate driver offers programmable delay, accurate current sensing, BEMF feedback, and features suited for safety-critical systems. It comes in a compact 9×9 mm, 57-pin QFN package. 

​​Jeff Strang, Qorvo Power Management GM, said, “The newest addition to our power management portfolio brings added flexibility to our customers’ BLDC designs, significantly reducing total solution size, design time and BOM cost. The ACT72350 provides the critical analog circuitry needed to implement a BLDC motor control system and can be paired with a variety of popular MCUs.”
