MP1923GR-Z

Overview

The MP1923GR-Z is a high-frequency half-bridge gate driver manufactured by Monolithic Power Systems. It features an 8 A output current capability and operates within a supply voltage range of 5 V to 17 V. The device supports a wide operating temperature range from -40°C to +125°C and consumes 2.6 mA of quiescent supply current. It is housed in an 8-pin QFN package designed for surface mount technology.

Feature Summary

• Provides high-side and low-side gate drive outputs for half-bridge configurations
• Supports high-frequency operation suitable for motor and ignition applications

Applications

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

Procurement Notes

Verify the specific suffix 'GR' corresponds to the QFN-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor data sheets prior to integration. Ensure the component matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component for designs requiring a dedicated half-bridge driver with moderate current drive capabilities. The QFN-8 package offers a compact solution for space-constrained layouts. Consider the 17 V maximum supply limit and 8 A peak output when sizing external components and ensuring adequate thermal management for the intended duty cycle.

Part Context

This part belongs to the MP1923 series of gate drivers from Monolithic Power Systems. It is categorized under Motor, Motion, and Ignition Controllers & Drivers within the PMIC product family. The GR suffix specifically denotes the QFN-8 package configuration, distinguishing it from other package variants like the GS (SOIC-8) version.

Replacement Considerations

The MP1923GS-Z serves as a package alternative offering identical electrical performance in an SOIC-8 footprint. Verify pinout compatibility and thermal characteristics when substituting between QFN and SOIC packages.
