MP1925HR-LF-Z

Overview

The MP1925HR-LF-Z is a high-frequency half-bridge gate driver manufactured by Monolithic Power Systems. It supports a supply voltage up to 100 V and delivers an output current of 4 A. The device operates within a temperature range of -40 °C to +125 °C and consumes 9 mA of quiescent current. It features two outputs and dissipates up to 2.66 W of power. The component is housed in an 8-lead QFN package designed for surface mount installation.

Feature Summary

• Supports high-voltage operation up to 100 V
• Delivers 4 A peak output current
• Operates across extended industrial temperature ranges

Applications

• Motor control systems
• Motion control applications
• Ignition system drivers

Procurement Notes

Verify the specific suffix LF-Z against the manufacturer datasheet to confirm lead-free compliance and packaging details. Ensure the QFN-8 footprint matches the target PCB layout. Cross-reference the 100 V rating with the actual circuit requirements to prevent overvoltage stress during procurement validation.

Selection Notes

Select this component when a half-bridge driver requires 100 V tolerance and 4 A drive capability. The QFN-8 package suits space-constrained designs. Verify thermal management needs given the 2.66 W dissipation rating. Confirm compatibility with the required switching frequency specifications for the intended load application.

Part Context

This part belongs to the MPS motor and motion driver category. It complements other half-bridge drivers like the MP1924AHS-LF-Z, which offers similar electrical characteristics but utilizes a SOIC-8 package instead of QFN-8. Both devices serve comparable roles in high-voltage switching applications within the same product family.

Replacement Considerations

MP1924AHS-LF-Z provides equivalent electrical performance with a different SOIC-8 package.
