MP18024HN-LF-Z

Overview

The MP18024HN-LF-Z is a half-bridge gate driver designed for N-channel MOSFETs, manufactured by Monolithic Power Systems. It operates within a supply voltage range of 9V to 16V and supports high-side bootstrap voltages up to 100V. The device features non-inverting inputs and delivers a peak output current of 4A. Typical propagation delays are characterized by rise and fall times of 15ns and 9ns respectively. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in an 8-SOIC package with an exposed pad.

Feature Summary

• Supports high-side bootstrap operation up to 100V for driving N-channel MOSFETs
• Provides 4A peak output current capability for efficient switching
• Features independent upper and lower channel control with non-inverting logic inputs

Applications

• High-frequency half-bridge power conversion circuits
• Motor drive systems requiring robust gate driving
• Industrial power management applications

Procurement Notes

Verify the specific suffix 'LF-Z' against the manufacturer's latest documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure compatibility with the intended PCB footprint, specifically the 8-SOIC EPAD outline. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when a 100V high-side rating and 4A drive strength are required for N-channel MOSFETs. Compare its 15ns/9ns transition times against system switching frequency requirements. Verify that the 9V-16V supply range aligns with the available control logic voltage levels and that the thermal performance of the SOIC-8 package meets the application's dissipation needs.

Part Context

This part belongs to the MP18024 series of half-bridge drivers from Monolithic Power Systems. It shares functional similarities with the MP18021 but offers higher drive current capabilities. The series targets applications needing reliable isolation between low-voltage control signals and high-voltage power stages without external level shifters.

Replacement Considerations

MP18024HN-LF-P is listed as a direct substitute. Verify pinout and electrical parameter equivalence before substitution.
