PAC5527AQM-T

Application Specific Microcontrollers Overview

The Qorvo PAC5527AQM-T is a 48V charge pump motor controller and driver optimized for high-speed BLDC motor control in battery-powered applications. It integrates a 150MHz Arm Cortex-M4F 32-bit microcontroller with a configurable power manager, Configurable Analog Front-End (CAFE), and Application Specific Power Driver (ASPD). The device features a charge pump DC/DC system for high-side gate drive, a buck-boost regulator for low-side drive, and four linear regulators. It includes 128kB flash, 32kB SRAM with ECC, and a 2.5MSPS ADC. The component operates within an input voltage range of 6V to 48V and is housed in a 48-pin 6mm x 6mm TQFN package.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'AQM' against the manufacturer's official datasheet to confirm pinout and functional variations compared to other PAC5527 variants. Confirm RoHS3 compliance status as per the latest documentation. Standard lead times may vary; check current availability directly with authorized distributors or Qorvo.

Application Specific Microcontrollers Selection Notes

Select this part for applications requiring a compact SoC solution for 48V BLDC motors. Ensure the design supports the 6V-48V input range. Verify that the integrated CAFE and ASPD capabilities meet the specific sensor monitoring and gate drive requirements without needing external components. Check thermal performance for the 48-TQFN package under expected load conditions.

Application Specific Microcontrollers Part Context

The PAC5527AQM-T belongs to the Qorvo PAC55xx series of intelligent motor controllers. This family integrates MCUs with power management and analog front-ends for BLDC/PMSM applications. Other members include PAC5523 and PAC5524, which may offer different voltage ratings or feature sets.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same package and functionality should be sought from the PAC55xx series, such as PAC5523 or PAC5524, after verifying electrical parameter compatibility and pin assignments via official datasheets.
