Procurement Notes

Verify the exact part number suffix against official MPS documentation to confirm package type and qualification status. Ensure compatibility with your system's voltage requirements and thermal management design. Check for any specific ordering codes that may affect availability or lead times. Confirm RoHS compliance and automotive qualification standards required for your application before finalizing procurement.

Selection Notes

Select this component when driving high-voltage switches in automotive environments requiring robust protection and high-frequency operation. Consider the 100 V supply range and 4 A drive capability for matching load requirements. Evaluate thermal performance given the 150°C maximum junction temperature. Compare with similar drivers if lower voltage or current ratings suffice for cost optimization.

Part Context

This part belongs to the MP18024 family of gate drivers, adapted for automotive-grade reliability. It shares functional similarities with other high-voltage drivers but is specifically optimized for harsh automotive conditions. The MPQ series designation indicates automotive qualification, distinguishing it from standard industrial variants.

Replacement Considerations

Direct replacements include MP18024HN-LF-Z for non-automotive use, though automotive qualification differs. Verify pin compatibility and electrical parameters before substituting. No other direct equivalents are confirmed in public data.
