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.

PAC5232EVK1

Active-Semi’s PAC5232EVK1 Evaluation Kit (EVK) is a complete hardware solution enabling users to evaluate and develop motor control applications around this powerful and versatile Arm®Cortex®-M0 based micro-controller. The module contains the PAC5232 Power Application Controller (MCU), IGBT inverter and debugging headers for serial interfaces and GPIO signals that may be used for debugging and evaluation.

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

ET-COLINK-1

The ET-COLINK-1 adapter allows the user to program and perform source level debugging of the target device using SWD from a PC. This adapter is required when using the CooCox CoIDE for development. This IDE and adapter will allow the user to program FLASH on the device, as well as perform source-level debugging of the application.
