PAC optimised for high speed brushless DC motor control

The Qorvo PAC5524 features Qorvo's Multi-Mode Power Manager (MMPM), which delivers an all-in-one power management solution for multiple types of power sources.

The MMPM features a configurable multi-mode switching supply controller that is capable of operating a SEPIC or buck converter and as many as four linear regulated voltage supplies.

The PAC5524 device is based on a 150MHz Arm Cortex-M4F 32-bit microcontroller and integrates a Configurable Analog-Front End (CAFE) and multiple Application-Specific Power Drivers (ASPDs).

The CAFE is comprised of three differential programmable-gain amplifiers, four single-ended programmable-gain amplifiers, digital-to-analogue converters, comparators, and several I/Os.

The ASPDs include integrated level shifters and pre-drivers designed for H-bridge, half-bridge, 3-phase, and general-purpose driving.

Qorvo's PAC5524 motor controller and driver offers 128 Kbytes of embedded flash memory and 32 Kbytes of SRAM memory.

It also features several serial communications interfaces, a 2.5 MSPS analogue-to-digital converter with programmable auto-sampling of up to 24 conversion sequences, and a flexible clock control system.

The highly integrated device is housed in an 8 mm × 8 mm package, making it suitable for compact, battery-powered BLDC motor applications that require additional I/O in order to implement value-add system control functionality.
