Qorvo PAC52400 Power Application Controllers
Qorvo PAC52400 Power Application Controllers are highly optimized System-On-Chips (SOCs) for controlling and powering next-generation small appliances, tools, consumer devices, and industrial equipment. These application controllers integrate a 50MHz Arm® Cortex®-M0 32-bit microcontroller core with Qorvo's proprietary Configurable Analog Front End™ and Application Specific Power Drivers™ to form the compact microcontroller-based motor control and drive SOC supporting a wide range of general purpose applications where cost and space are essential. Qorvo PAC52400's microcontroller features up to 32kB of embedded FLASH and 8kB of SRAM memory, a high-speed 10-bit 1µs analog-to-digital converter (ADC) with dual auto-sampling sequencers, 5V/3.3V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces.
The Multi-Mode Power Manager (MMPM) provides a power management solution for a simple power source topology. The MMPM integrates linear regulated voltage supplies to power the internal analog and digital blocks. The Application Specific Power Drivers (ASPD) are medium-voltage power drivers designed for each target set of control applications, including half-bridge, H-bridge, 3-phase, intelligent power module (IPM), and general-purpose driving. The Configurable Analog Front End (CAFE) comprises differential programmable gain amplifiers, single-ended programmable gain amplifiers, comparators, digital-to-analog converters, and I/Os for programmable and inter-connectible signal sampling, feedback amplification, and sensor monitoring of multiple analog input signals. The PAC52400 Power Application Controllers enable a wide range of compact applications with highly integrated power management, driving, feedback, and control for DC supply up to 44V.
