The PAC5523 is a custom Power Application Controller TM (PAC) product that is optimized for high-speed BLDC motor control. The PAC5523 integrates a 150MHz ARM Cortex-M4F 32-bit microcontroller core with Active-Semi’s proprietary and patent-pending Multi-Mode Power Manager TM, Configurable Analog Front-EndTM and Application Specific Power DriversTM to form the most compact microcontroller-based power and motor control solution available. The PAC5523 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, intelligent power module (IPM), 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. 

Multi-mode switching supply controller configurable for DC/DC Buck or SEPIC topologies 

Direct battery supply from 4.5V – 20V 

4 Linear regulators with power and hibernate management Power and temperature monitor, warning, fault detection
