PAC55724L

72 V BLDC Controller and Driver with Integrated Multimode Power Manager and Configurable AFE - extended I/O

Qorvo's PAC55724 expands Qorvo's broad portfolio of full-featured Power Application Controller® (PAC) products - highly optimized System On Chip (SOC) for controlling and powering next generation smart energy appliances, devices, and equipment – by adding new features such as Cycle By Cycle (CBC), Enhanced Sample And Hold (S&H), Windowed Watchdog Timer, and more.
This application controller integrates a 150 MHz 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 the most compact microcontroller-based power and general purpose application systems.
The product's microcontroller features up to 128 kB of embedded FLASH and 32 kB of SRAM memory, a high-speed 12-bit 2.5 MSPS analog-to-digital converter (ADC) with dual auto-sampling sequencers, 5 V/3.3 V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces.
