The PAC5232 belongs to Active-Semi’s Power Application Controller® (PAC®) family. The PAC® family of products are highly-optimized SOC devices that can implement BLDC or PMSM programmable motor controller and driver in a single integrated IC. The PAC5232 integrates a FLASH-based MCU, Power Management , High-side and low-side Gate Drivers and Signal-Conditioning components in a single product.
The PAC5232 is optimized for 48V to 120V battery-powered BLDC applications such as garden tools or battery-powered bikes and scooters.
The PAC5232 contains a 50MHz Arm® Cortex®-M0 with 32kB of FLASH that can be used to implement high-performance motor control and supervisory applications. The MCU also contains motor control peripherals such as 10b 1MSPS dual auto-sequencer ADC, PWM timers with hardware dead-time insertion, etc. The Multi-Mode Power Manager™ (MMPM) contains a 160V Buck DC/DC controller and power management components for powering the IC and other PCB system power supplies. The Application-Specific Power Drivers™ provide integrated gate drivers for use with an external inverter. The Configurable Analog Front-End™ (CAFE) provides signal-chain components such as differential and single-end amplifiers, comparators and DACs.
Advantages of our Intelligent Motor Control
|Programmable 32-bit MCU||Allows implementation of high-performance advanced control algorithms such as Field Oriented Control (FOC), Sensorless BEMF, Sensored BLDC and serial communications protocols|

The PAC5232EVK1 can be used with Active-Semi’s BLDC/BEMF or FOC firmware and Windows GUI for evaluation and debugging of the application. The ET-COLINK-1 may be used for connecting the EVK to a Windows PC using a USB cable, for programming and debugging using an IDE. The ET-UARTISO-1 may be used for connecting the Windows PC to the device’s UART for the Windows GUI.
Supporting Evaluation Tools
PAC52xx FOC Application Firmware Installer for the PAC52XX FOC application firmware designed to show case motor control using sensorless Field Oriented Control (FOC) on all members of the PAC52XX family. The installer contains example FOC application source code, Windows graphical user interface (GUI), and documentation to allow the user to configure the system to work with their target motor. Project files for CooCox CoIde, IAR Systems Embedded Workbench for ARM (EWARM) and Keil uVision are included. The FOC application provides a configurable set of features to meet many different application requirements such as sensorless position/speed estimator, start-in-motion (SIM), initial position detection (IPD), open phase detection (OPD), field weakening and others.
PAC52xx Software Development Kit
Installer for the PAC52XX Software Development Kit (SDK) that provides register level definitions and peripheral driver APIs for developing ARM M0 application firmware on all PAC52XX devices. The PAC52XX SDK is a unified SDK that supports Keil µVision IDE, IAR Systems Embedded Workbench for ARM (EWARM) IDE, and GCC tool chains.
PAC52XX IDE Support
Development of application firmware for PAC52XX ARM Cortex® M0 is made easy with standard integrated development environments (IDEs). Several of the most popular integrated IDEs contain support for PAC52XX devices including Keil uVision, IAR Systems Embedded Workbench for ARM, and Coocox CoIDE.
