Model Number: PAC5256

Intelligent Motor Controller from Qorvo

600 V BLDC / PMSM Motor Controller and Driver

Status: Standard | Data Sheet:

| RoHS Compliance: Rohs Compliant

Overview

Qorvo’s PAC5256 belongs to Qorvo’s Power Application Controller® (PAC) product family. This family features highly-optimized SOC devices that can implement BLDC or PMSM programmable motor controller and driver in a single integrated IC.

The product integrates a FLASH-based MCU, power management, high-side and low-side gate drivers and signal-conditioning components in a single product.

PAC5256 is optimized for AC-powered BLDC or PMSM motor control applications such as AC-powered fans, white goods or compressors. PAC5256 also includes optimized hardware support and software libraries for the IEC/UL 60730 Class B Safety standard.

PAC5256 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 10-bit 1 MSPS dual auto-sequencer ADC, PWM timers with hardware dead-time insertion, etc. The product contains an integrated N-CH Buck DC/DC controller, a 5V / 200mA converter and multiple LDOs for system and power management components for he 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.
