Qorvo PAC5524 motor controller and driver

Qorvo’s PAC5524 motor controller and driver features the company’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 multimode switching supply controller that is capable of operating a SEPIC or buck converter and as many as four linear regulated voltage supplies.

The device is based on a 150 MHz Arm Cortex-M4F 32-bit microcontroller and integrates a Configurable Analog-Front End (CAFE) and multiple Application-Specific Power Drivers (ASPDs). The CAFE comprises three differential programmable-gain amplifiers, four single-ended programmable-gain amplifiers, digital-to-analog converters, comparators and several I/Os. The ASPDs include integrated level shifters and pre-drivers designed for H-bridge, half-bridge, three-phase and general-purpose driving.

The motor controller and driver offers 128 KB of embedded flash memory and 32 KB of SRAM memory. It also features several serial communications interfaces, a 2.5 MSPS analog-to-digital converter with programmable auto-sampling of up to 24 conversion sequences and a flexible clock control system.

The 70 V Power Application Controller (PAC) is optimised for high-speed brushless DC (BLDC) motor control. The highly integrated device is housed in an 8 x 8 mm package, making it a suitable choice for compact, battery-powered BLDC motor applications that require additional I/O in order to implement value-add system control functionality.
