Qorvo PAC5556 Power Application Controllers®
Qorvo PAC5556 Power Application Controllers® integrate a flash-based high-performance MCU, power management, high-side and low-side gate drivers, and signal-conditioning components in a single optimized System on Chip (SoC). Based on the Arm® Cortex®-M4F core, the PAC5556 is optimized for AC-powered brushless DC (BLDC) or permanent magnet synchronous motor (PMSM) control applications such as AC-powered fans, white goods, or compressors. Qorvo PAC5556 also includes optimized hardware support and software libraries for the IEC/UL 60730 Class B safety standard.The PAC5556 contains a 150MHz Arm Cortex-M4F with a 128kB flash that can be used to implement high-performance motor control and supervisory applications. The MCU also contains motor control peripherals such as 12-bit 2.5MSPS dual auto-sequencer ADC and PWM timers with hardware dead-time insertion. The PAC5556 includes an integrated N-channel Buck DC-DC controller, a 5V/200mA converter, and multiple LDOs for system and power management components for 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.
Qorvo PAC5556 is offered in a 10mm x 10mm QFN1010-52 package.
