Qorvo ACT72350 BLDC Motor Drivers
Qorvo ACT72350 BLDC Motor Drivers are integrated 3-phase BLDC/PMSM drivers optimized for driving medium voltage tri-phase BLDC/PMSM motors. These 160V drivers are interfaced through the tri-phase inverter PWM control input signals. The ACT72350 is fully equipped with Qorvo’s proprietary highly configurable Power Manager. The Configurable Power Manager (CPM) provides an “all-in-one” efficient power management solution for multiple types of power sources. These motor drivers are made available for easy access with the externally provided microcontroller core for all analog resources. The ACT72350 motor drivers are available in a 57-pin, 9mm x 9mm TQFN package. These drivers are well suited for power tools, garden tools, motor controllers, drone/RC, E-bike, E-vehicle, ped-electric bikes, and light HEV.
