PAC5527AQMSR

Application Specific Microcontrollers Overview

The Qorvo PAC5527AQMSR is a 48V charge pump motor controller and driver optimized for high-speed BLDC motor control in battery-powered applications. It integrates a 150MHz Arm Cortex-M4F 32-bit microcontroller with a configurable power manager, Configurable Analog Front-End (CAFE), and Application Specific Power Driver (ASPD). The device features a charge pump DC/DC system for high-side gate drive, a buck-boost regulator for low-side drive, and four linear regulators. Key electrical parameters include an input voltage range of 6V to 48V, 128kB embedded flash, 32kB SRAM with ECC, and a 2.5MSPS ADC. It operates within a temperature range of -40°C to +125°C and is housed in a 48-pin 6mm x 6mm TQFN package.
