MP1921HR-A-LF-Z

Overview

The MP1921HR-A-LF-Z is a high-frequency half-bridge gate driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 9 V to 18 V and delivers a peak output current of 2.5 A. The device features non-inverting logic configuration with propagation delays up to 16 ns, rise times of 12 ns, and fall times of 9 ns. Designed for surface-mount installation, it utilizes an SOIC-8 package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• High-speed switching capability with fast rise and fall times suitable for high-frequency applications
• Robust drive strength providing 2.5 A output current for efficient power stage control
• Wide operating temperature range ensuring reliability in demanding thermal environments

Applications

• Motor drive systems requiring precise half-bridge control
• Industrial motor motion controllers
• Ignition system drivers

Procurement Notes

Verify the specific suffix HR against official MPS documentation to confirm the SOIC-8 package variant. Ensure compatibility with existing board layouts and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when a half-bridge driver with 2.5 A drive strength and high-frequency performance is required. Consider the SOIC-8 package constraints and the 9 V to 18 V supply voltage range during circuit design.

Part Context

This part belongs to the MP1921 series of half-bridge gate drivers from Monolithic Power Systems. It shares functional similarities with other members like the MP1921HS but differs in package type and specific electrical characteristics defined by the suffix.

Replacement Considerations

MP1921HS-A-LF is a documented alternative within the same series offering similar electrical performance in a different package.
