PAC5527 48V Charge Pump Motor Controller and Driver for BLDC Motors 1 Product Overview The PAC5527 is a 48V Power Application Controller (PAC) product that is optimized for high-speed motor control and driving for battery powered BLDC motors. The PAC5527 integrates a 150MHz Arm Cortex -M4F 32-bit microcontroller core with a highly TM configurable Power Manager, Active-Semis proprietary and patent-pending Configurable Analog Front-End and Application Specific TM Power Drivers to form the most compact microcontroller-based power and motor control solution available. 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 and general-purpose timers and several serial communications interfaces. The Power Manager provides all-in-one efficient power management solution for the application. It features a charge pump, buck- boost converter and four linear regulated voltage supplies. The Application Specific Power Drivers (ASPD) are power drivers designed for half bridge, H-bridge, 3-phase, 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 PAC5527 is available in a 48-pin, 6x6mm TQFN package.
