Qorvo PAC55710 72V BLDC Motor Controller & Driver

Qorvo PAC55710 72V BLDC Motor Controller and Driver is a full-featured, highly optimized System-on-Chip (SOC) that expands Qorvo's portfolio of Power Application Controller® (PAC) products. The PAC55710 controls and powers next-generation smart energy appliances, devices, and equipment with integrated VDS sensing, Cycle By Cycle (CBC), Enhanced Sample And Hold (S&H), and a Windowed Watchdog Timer. This application controller integrates a 150MHz Arm® Cortex®-M4F 32-bit microcontroller core with Qorvo's proprietary and patent-pending Multi-Mode Power Manager™, Configurable Analog Front End™, and Application Specific Power Drivers™. These features enable compact microcontroller-based power and general-purpose application systems.

The Qorvo PAC55710's microcontroller features up to 128kB of embedded FLASH and 32kB of SRAM memory, a high-speed 12-bit 2.5MSPS analog-to-digital converter (ADC) with dual auto-sampling sequencers, 3.3V I/Os, flexible clock sources, timers, a versatile 15-channel PWM engine, and several serial interfaces.
