Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'AQM' matches the required pinout and thermal pad configuration. Confirm that the 48V rating aligns with the system's maximum supply voltage. Ensure the 48-WFQFN package dimensions fit the PCB layout constraints. Check for any regional compliance certifications required for the target market.

Application Specific Microcontrollers Selection Notes

Select this component when a 48V input range is required for BLDC applications. Choose PAC5526 over PAC5523 if higher voltage tolerance is needed. Consider PAC5524 if a higher pin count and larger package are necessary for complex layouts. Evaluate the integrated power management capabilities against external component requirements.

Application Specific Microcontrollers Part Context

This part belongs to Qorvo's PAC55xx series of intelligent motor controllers. These devices combine MCU cores with power management and driver stages. The PAC5526 specifically targets 48V systems, distinguishing it from lower or higher voltage variants within the same product family designed for different automotive and industrial standards.

Application Specific Microcontrollers Replacement Considerations

PAC5523AQM-T serves as a lower voltage alternative for 72V systems. PAC5524AQM-T offers a high-pin-count option for more complex designs. Verify pin compatibility and firmware support before substituting with other PAC55xx series members.
