Overview
The Qorvo PAC5527QMST is a 48V Brushless DC (BLDC) motor controller and driver optimized for high-speed control in battery-powered applications. It integrates a 150MHz Arm Cortex-M4F microcontroller, a configurable analog front-end, and application-specific power drivers within a 48-pin TQFN package. The device operates on an input voltage range of 6V to 48V with a typical supply current of 11mA. It features a charge pump DC/DC system for high-side gate drive, a buck-boost regulator for low-side drive, and four linear regulators. The integrated MCU includes 128kB flash, 32kB SRAM, and a 2.5MSPS ADC.
Feature Summary
- Integrates a 150MHz Arm Cortex-M4F microcontroller with hardware floating-point unit and DSP instructions for efficient processing.
- Includes a proprietary Configurable Analog Front-End with programmable gain amplifiers and comparators for flexible sensor monitoring.
- Features Application Specific Power Drivers capable of up to 1A programmable gate drive current with 100% duty cycle support.
- Provides a comprehensive power management solution with charge pump, buck-boost converter, and multiple linear regulators.
Applications
- High-speed BLDC motor control for battery-powered devices
- Compact power and motor control solutions requiring miniaturization
- Smart home appliances and systems requiring integrated motor drive
Procurement Notes
Verify the specific suffix 'QMST' against official Qorvo documentation to confirm tape-and-reel packaging details and moisture sensitivity classification. Ensure compatibility with the PAC5527A development kit if software migration is required. Confirm that the 48-TQFN thermal pad requirements are met by the target PCB layout for optimal heat dissipation during operation.
Selection Notes
Select this component when designing compact, battery-operated systems requiring high-performance BLDC control. The integration of the MCU, power management, and analog front-end reduces bill-of-materials count. Consider the 150MHz processing speed and 2.5MSPS ADC sampling rate for applications demanding precise feedback and fast response times.
Part Context
The PAC5527 series belongs to Qorvo's Power Application Controller (PAC) family, designed to simplify motor control design. This model specifically targets 48V systems, distinguishing it from higher voltage variants like the PAC55723 or lower voltage options. It represents a system-level solution combining digital control with analog power stages.
Replacement Considerations
The PAC5527AQMSR is a related variant within the same product line. Verify pinout and functional equivalence before substitution. No other direct public substitutes are confirmed in the provided data.
