MPQ18021HN-A-AEC1-LF-P

Overview

The MPQ18021HN-A-AEC1-LF-P is a high-frequency half-bridge gate driver designed for automotive applications, qualified to AEC-Q100 standards. It features a supply voltage range of 9 V to 18 V and supports up to 100 V on the bootstrap terminal. The device provides independent control of high-side and low-side channels with matched propagation delays under 5 ns. Typical switching performance includes a 12 ns rise time and a 9 ns fall time when driving a 1 nF load at 12 V. It integrates an internal bootstrap diode and offers undervoltage lockout protection for both drivers.

Feature Summary

• AEC-Q100 qualified for automotive reliability requirements
• Integrated bootstrap diode reduces external component count
• Independent high-side and low-side channel control with tight delay matching
• Undervoltage lockout protection prevents improper MOSFET operation

Applications

• Automotive powertrain systems
• Motor control circuits
• High-voltage DC-DC converters

Procurement Notes

Verify the specific suffix 'A' indicates automotive grade qualification distinct from the standard MP18021HN-LF-P. Confirm package type matches design requirements, as variants exist in SOIC-8 EPAD and QFN-8. Ensure compatibility with system voltage levels and thermal management needs before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring robust automotive-grade gate driving with minimal external parts. The integrated bootstrap diode simplifies layout compared to discrete solutions. Consider the 100 V VBST rating for high-side drive capabilities. Verify that the 9 V minimum supply voltage aligns with the system's available power rails during all operating conditions.

Part Context

This part belongs to the MP18021 family of half-bridge gate drivers from Monolithic Power Systems. While the standard MP18021HN-LF-P serves general industrial markets, the MPQ variant adds AEC-Q100 qualification for automotive use. It shares core electrical characteristics but meets stricter automotive reliability and temperature standards.

Replacement Considerations

The MP18021HN-LF-P is a pin-compatible non-automotive alternative. Verify if automotive qualification is strictly required; otherwise, the standard version may suffice. No other direct substitutes are confirmed in public documentation without additional verification.
