Qorvo PAC52410 Power Application Controller®

Qorvo PAC52410 Power Application Controller^® (PAC) devices are highly optimized for controlling and powering next-generation smart energy appliances, devices, and equipment. These application controllers integrate a 50MHz Arm^® Cortex^®-M0 32-bit microcontroller core with Qorvo's proprietary and patent-pending Multi Mode Power Manager™ (MMPM), Configurable Analog Front End™ (CAFE), and Application Specific Power Drivers™ (ASPD) to form compact microcontroller-based power and general purpose application systems ranging from digital power supply to motor control. The PAC52410 microcontroller features up to 32kB of embedded FLASH, 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 MMPM provides an “all-in-one” efficient power management solution for multiple types of power sources. The MMPM features a configurable multi-mode switching supply controller capable of operating in buck or SEPIC mode and up to four linear regulated voltage supplies. The ASPDs are high-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 CAFE comprises differential programmable gain amplifiers, single-ended programmable gain amplifiers, comparators, digital-to-analog converters (DACs), and I/Os for programmable and interconnectible signal sampling, feedback amplification, and sensor monitoring of multiple analog input signals. Together, these modules and microcontroller enable a wide range of compact applications with highly integrated power management, driving, feedback, and control for DC supply of up to 40V.
