Qorvo PAC52710/11 Power Application Controllers

Qorvo PAC52710/11 Power Application Controllers (PACs) are highly optimized System-On-Chips (SOCs) for controlling and powering next-generation devices. These controllers integrate 50MHz Arm^® Cortex^®-M0 32-bit microcontroller core with patent-pending Multi-Mode Power Manager™ (MMPM), Application Specific Power Drivers™(ASPD), and Configurable Analog Front End™(CAFE). The PAC52710/11 PACs feature up to 32kB of embedded FLASH, a 10-bit 1µs Analog-to-Digital Converter (ADC), 8kB of SRAM memory, flexible clock sources, and 5V/3.3V I/Os.

The PAC52710/11 full-featured PACs include programmable over-current shut-down, programmable comparator hysteresis and blanking, V_DS sensing, and advanced cycle-by-cycle protection. These controllers are used in E-mobility, small appliances, power and garden tools, pumps, fans, and robotics.
