• AEC-Q100 qualified for automotive reliability
• Integrated overcurrent and thermal protection
• Smart high-side switching capability

Applications

• Automotive power distribution networks
• High-side load switching in vehicle electronics
• Protection circuits for 12V or 24V automotive loads

Procurement Notes

Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm that the AEC-Q100 qualification status aligns with your automotive project requirements. Check the latest datasheet for any updates regarding pinout or electrical characteristics before finalizing the design. Ensure compatibility with your system's voltage levels and thermal management strategy.

Selection Notes

Select this component when a single-channel high-side switch with automotive certification is required. Consider the 36 V maximum input voltage and 1 A continuous output current limits. Evaluate the 80 mOhm on-resistance against your power loss constraints. Verify that the QFN-8 package fits your PCB layout and thermal dissipation needs compared to alternative packages in the MPQ5871 series.

Part Context

This part belongs to the MPQ5871 series of smart load switches from Monolithic Power Systems. It is specifically engineered for automotive environments, distinguishing itself through AEC-Q100 qualification. The series offers various channel configurations and voltage ratings, but this specific model focuses on a single channel optimized for standard automotive bus voltages up to 36 V.

Replacement Considerations

Check the official MPS documentation for direct cross-references within the MPQ5871 family. Verify if variants with different channel counts or resistance values meet your specific electrical requirements. Ensure any substitute maintains the same AEC-Q100 qualification level.
