PAC5524 High Pin-Count 70V Motor Controller and Driver for BLDC Motors 1 Product Overview The PAC5524 is a Power Application Controller (PAC) product that is optimized for high-pin count and high-speed BLDC motor control. The PAC5524 integrates a 150MHz Arm Cortex -M4F 32-bit microcontroller core with Active-Semis proprietary and patent- TM TM TM pending Multi-Mode Power Manager , Configurable Analog Front-End and Application Specific Power Drivers to form the most compact microcontroller-based power and motor control solution available. The PAC5524 microcontroller features 128kB of embedded FLASH and 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 Multi-Mode Power Manager (MMPM) provides all-in-one efficient power management solution for multiple types of power sources. It features a configurable multi-mode switching supply controller capable of operating a buck or SEPIC converter and up to 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 PAC5524 is packaged in an 8x8mm, 64-lead QFN package with for compact battery-powered BLDC motor applications. PAC5524 Data Sheet Rev.
