Procurement Notes
Verify the complete part number including suffixes such as -P for reel packaging when ordering. Confirm that the specific variant matches the required automotive qualification and package type. Cross-reference the manufacturer datasheet to ensure compatibility with system voltage ranges and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component for designs requiring a compact, single-output LED driver with integrated power switching. Ensure the application input voltage falls between 4.5 V and 16 V. Verify that the QFN-24 package fits the PCB layout constraints and that the 80 mA output current meets the LED load requirements without exceeding thermal limits.
Part Context
This part belongs to the MPQ7221 series of LED drivers from Monolithic Power Systems. It is specifically designed for automotive lighting applications where space efficiency and regulatory compliance are critical. The GRE-AEC1 designation indicates its automotive qualification and specific package configuration.
Replacement Considerations
Consult official MPS documentation for direct pin-to-pin replacements or functional equivalents within the same automotive qualification tier. Verify that any substitute maintains the same buck topology, voltage range, and AEC-Q100 status.
