MPQ1924HS-LF-Z

Overview

The MPQ1924HS-LF-Z is a high-frequency, 100V half-bridge gate driver manufactured by Monolithic Power Systems. It integrates independent low-side and high-side N-channel power MOSFET drivers within an 8-SOIC package. The device supports non-inverting control signals and operates with a supply voltage range of 8V to 20V. It features a quiescent current of 2mA and withstands junction temperatures up to +125°C. Designed for robust performance, it includes comprehensive protection mechanisms against over-current, over-temperature, over-voltage, and short-circuit conditions.

Feature Summary

• Integrates independent high-side and low-side driver channels for precise half-bridge control
• Provides comprehensive fault protection including over-current, over-temperature, over-voltage, and short-circuit detection
• Supports non-inverting logic input for straightforward interface with control systems

Applications

• High-frequency motor drive systems
• Industrial motion control applications
• Ignition controller circuits

Procurement Notes

Verify the specific suffix (LF-Z) to confirm lead-free compliance and tape-and-reel packaging configuration. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm compatibility with your design specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact 8-SOIC solution is required for driving 100V N-channel MOSFETs in half-bridge topologies. It is suitable for designs demanding high switching frequencies and integrated fault protection. Consider the thermal dissipation capabilities of the SOIC-8 package relative to the expected load current and ambient operating temperature constraints.

Part Context

This component belongs to the MPQ series of automotive-grade or industrial-grade power management ICs from Monolithic Power Systems. It functions as a specialized gate driver within the broader category of motor and ignition controllers. The device complements other MPS offerings by providing integrated power stage control in a small footprint, reducing external component count compared to discrete driver solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings if considering alternative manufacturers' half-bridge drivers.
