The PAC5253 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 PAC5253 integrates a FLASH-based MCU, Power Management, High-side and low-side Gate Drivers and Signal-Conditioning components in a single product. The PAC5253 is optimized for AC-Powered BLDC or PMSM motor control applications such as AC-powered fans, white goods or compressors in a low pin-count package. The PAC5253 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 Flyback 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.

Supporting Evaluation Tools
The ET-UARTSWD adapter is the preferred adapter for evaluation of PAC devices/firmware and combines a USB to UART adapter with SWD debugger connector adaptation into a single board with isolation. The ET-UARTISO-1 adapter provides only the USB to UART adapter with isolation for Active-Semi application GUI communications.
|The ET-UARTISO-1 adapter is a USB to UART adapter for Active-Semi application GUI communications with the PAC device UART, and can be used for evaluation and debugging of PAC applications.|
