MP1925HR-LF-P

Overview

The MP1925HR-LF-P is a high-frequency half-bridge gate driver manufactured by Monolithic Power Systems. It supports a supply voltage range of 8 V to 15 V and delivers a peak output current of 4 A. The device operates within an extended temperature range from -40°C to +125°C. It features two outputs and consumes 9 mA of quiescent current. The component is housed in a QFN-8 surface-mount package with a power dissipation rating of 2.66 W.

Feature Summary

• High-frequency half-bridge gate driver architecture
• Robust 4 A peak output current capability
• Extended industrial operating temperature range

Applications

• Motor control systems
• Motion control applications
• Ignition drivers

Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging configuration, as datasheets may reference 'Z' variants. Ensure compatibility with QFN-8 footprint requirements and validate thermal management for 2.66 W dissipation. Confirm RoHS compliance status through manufacturer declarations prior to integration.

Selection Notes

Select this component when a dual-output half-bridge driver with 4 A drive strength is required. The QFN-8 package suits space-constrained designs. Verify that the 8 V to 15 V supply range aligns with system power rails. Consider the -40°C to +125°C range for industrial environments.

Part Context

This part belongs to the MPS motor and motion driver portfolio. It complements other half-bridge drivers like the MP1924 series. The HR variant typically denotes specific pinout or thermal characteristics within the family. It serves as a dedicated interface between logic controllers and power switches.

Replacement Considerations

MP1924HS-LF-P offers similar half-bridge functionality but uses an SOIC-8 package instead of QFN-8. MPQ1925HR-LF-Z provides comparable electrical performance with an extended maximum temperature of +150°C. Verify pinout and thermal pad configurations before substitution.
