Mouser Electronics has now stocked the PAC5524 motor controller and driver from Qorvo. The 70 V Power Application Controller (PAC) features increased input/output (I/O) capability and is optimized for a high-speed brushless DC (BLDC) motor control.
The Qorvo PAC5524, available from Mouser Electronics, 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 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 is comprised of 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, 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. The PAC5524 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 highly integrated device is housed in an 8 mm × 8 mm package, making it an ideal choice for compact, battery-powered BLDC motor applications that require additional I/O in order to implement value-add system control functionality.
