Application Specific Microcontrollers datasheet and documents for PAC5524QFSR
Application Specific Microcontrollers Overview
The Qorvo PAC5524QFSR is a high-pin-count Power Application Controller (PAC) designed for brushless DC (BLDC) motor control. It integrates a 150MHz Arm Cortex-M4F microcontroller, a Multi-Mode Power Manager (MMPM), a Configurable Analog Front-End (CAFE), and Application-Specific Power Drivers (ASPD). The device supports input voltages up to 20V directly and features three low-side and three high-side gate drivers with 1.5A drive capability. Key specifications include 128kB flash, 32kB SRAM with ECC, and a 2.5MSPS ADC. It operates within a temperature range of -40°C to +125°C and is housed in an 8mm x 8mm, 64-pin QFN package.

- Industrial motor control systems
- High-pin-count power management solutions
Application Specific Microcontrollers Part Context
The PAC5524QFSR belongs to the PAC5524 series from Qorvo's Power Application Controller portfolio. This family targets high-performance motor control by combining digital processing with analog front-end and power driver capabilities on a single chip. The specific suffix 'QFSR' indicates the automotive-grade qualification (Q), the 64-pin QFN package (F), and the reel tape packaging format (SR).
Application Specific Microcontrollers Replacement Considerations
Direct replacements must match the 64-pin QFN footprint and 70V/20V rating profile. Verify pin compatibility with other PAC5524 variants such as PAC5524AQF-T. Ensure the substitute supports the required MMPM topology and gate driver current specifications.
