Qorvo PAC5527 48V Charge Pump Motor Controller & Driver

Qorvo PAC5527 48V Charge Pump Motor Controller and Driver is optimized for high-speed motor control and driving for battery-powered BLDC motors. The PAC5527 integrates a 150MHz Arm^®Cortex^®-M4F32-bit microcontroller core with a highly configurable Power Manager, Qorvo’s proprietary and patent-pending Configurable Analog Front-End™ and Application Specific Power Drivers™. This forms a compact microcontroller-based power and motor control solution.

The Power Manager offers an “all-in-one” efficient power management solution for an application. Additionally, the Power Manager features a charge pump, buck-boost converter, and four linear regulated voltage supplies. The Application Specific Power Drivers (ASPD) are power drivers intended for a half-bridge, H-bridge, 3-phase, and general-purpose driving. The Configurable Analog Front End (CAFE) contains 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 PAC5527 features 128kB of embedded FLASH, 32kB of SRAM memory, a 2.5MSPS analog-to-digital converter (ADC) with programmable auto-sampling of up to 24 conversion sequences, 3.3V IO, flexible clock control system, PWM, general-purpose timers, and several serial communications interfaces. The PAC5527 48V Charge Pump Motor Controller and Driver is available in a 48-pin, 6mm x 6mm TQFN package.
