PAC5524AQF-T

Application Specific Microcontrollers Overview

The PAC5524AQF-T is a high-pin-count 70V motor controller and driver optimized for Brushless DC (BLDC) motors. It integrates a 150MHz Arm Cortex-M4F 32-bit microcontroller, Multi-Mode Power Manager (MMPM), Configurable Analog Front-End (CAFE), and Application Specific Power Driver (ASPD). The device features 128kB flash, 32kB SRAM with ECC, and a 2.5MSPS ADC supporting up to 24 conversion sequences. It operates within an input voltage range of 6V to 70V, utilizing a buck or SEPIC converter topology managed by the MMPM.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'AQF' against the official Qorvo datasheet to confirm package type and temperature grade. Confirm availability status as distribution channels may indicate restricted supply. Ensure the reel packaging quantity aligns with production requirements.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring integrated power management and motor driving in a single IC. The 64-lead QFN package suits space-constrained applications. Verify that the 70V input rating and 1.5A gate drive current meet the specific motor load requirements.

Application Specific Microcontrollers Part Context

This part belongs to the PAC5524 family of Power Application Controllers. The PAC5524A variant contains the PAC55xx MCU v2, whereas the standard PAC5524 contains MCU v1. Both share the same external interface and power management architecture but differ in internal MCU revisions.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the PAC55xx series or PAC5571x family for potential compatibility based on pinout and feature overlap.
