PAC5527QM-T

Application Specific Microcontrollers Overview

The PAC5527QM-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 MCU with 128kB Flash and 32kB SRAM, a configurable analog front-end (CAFE), and application-specific power drivers. The device features a charge pump DC/DC system for high-side gate drive, a buck-boost regulator for low-side drive, and four LDOs. It 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 'T' indicates tape-and-reel packaging when sourcing. Confirm the 27-week standard lead time with the manufacturer or authorized distributors. Ensure compatibility with the 48-TQFN (6x6) footprint during PCB layout. Check RoHS3 compliance status as per the latest datasheet revision.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring integrated motor drive and control in a small form factor. The 48V rating suits battery-operated systems. Consider the 128kB Flash and 32kB SRAM limits for complex control algorithms. The CAFE block supports flexible sensor interfacing for precise current and position feedback.

Application Specific Microcontrollers Part Context

The PAC5527 belongs to Qorvo's PAC55xx series of intelligent motor controllers. This family combines high-voltage power stages with ARM Cortex-M cores. The PAC5527 specifically targets 48V systems, distinguishing it from higher voltage variants like the PAC5523 (70V) or other series members.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other PAC55xx series devices based on voltage ratings and pin compatibility if alternatives are required.
