Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The Qorvo PAC55711 70V BLDC motor controller/Driver expands Qorvo's full-featured Power Application Controller ® (PAC) portfolio. The device is a highly optimized system-on-chip (SoC) for controlling and powering the next generation of smart energy appliances, devices and devices. These controllers/drives feature VDS detection, cycle by cycle (CBC), Enhanced Sampling and Hold (S&H), window watchdog timers, and hardware-based nBRAKE/nDRVDIS to support secure applications with external secure MCUS.

The PAC55711 application controller combines a 150MHz Arm® Cortex-M4F 32-bit microcontroller core with Qorvo's proprietary and patent-pending multi-mode Power Array™, configurable analog Front End ™, and application Specific Power Architecture™ integrates to form a microcontroller-based compact power supply and general-purpose application system. The PAC55711 microcontroller features up to 128kB of embedded flash memory and 32kB of SRAM memory, a high-speed 12-bit 2.5MSPS analog-to-digital converter (ADC) with dual automatic sampling sequencer, 5.0V/3.3V I/O, a flexible clock source, timers, a multifunctional 14-channel PWM engine, and multiple serial interfaces.
