Qorvo PAC55711 70V BLDC Motor Controller & Driver
Qorvo PAC55711 70V BLDC Motor Controller/Driver expands Qorvo's broad portfolio of full-featured Power Application Controller® (PAC) products. The PAC55711 devices are highly optimized System-on-Chip (SOC) for controlling and powering next-generation smart energy appliances, devices, and equipment. These controllers/drivers feature VDS Sensing, Cycle By Cycle (CBC), Enhanced Sample And Hold (S&H), a Windowed Watchdog Timer, and hardware-based nBRAKE/nDRVDIS for safety-based applications with external safety MCU support.
The Qorvo PAC55711 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™ to form compact microcontroller-based power and general-purpose application systems. The PAC55711's microcontroller features up to 128kB of embedded FLASH and 32kB of SRAM memory, a high-speed 12-bit 2.5 MSPS analog-to-digital converter (ADC) with dual auto-sampling sequencers, 5.0V/3.3V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces.
