MP1923GS-Z

Overview

The MP1923GS-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. It utilizes an SOIC-8 surface-mount package and consumes 2.6 mA of quiescent supply current. The component includes two outputs with a saturation voltage of 70 mV and a power dissipation rating of 1.3 W.

Feature Summary

• High-frequency operation for efficient switching applications
• Integrated high-side and low-side driver topology
• Robust thermal performance across extended temperature ranges

Applications

• Motor control systems
• Motion control drives
• Ignition controller circuits

Procurement Notes

Verify the specific suffix Z indicates RoHS compliance status during procurement. Confirm the SOIC-8 package dimensions match the target PCB footprint requirements. Ensure the supply voltage does not exceed the 17 V maximum limit under all operating conditions. Check humidity sensitivity levels for proper storage and handling procedures before assembly.

Selection Notes

Select this component when an 8 A peak drive current is required for half-bridge configurations. Consider the 5 V to 17 V input range compatibility with existing logic levels. Evaluate the SOIC-8 package size against available board space constraints. Assess thermal management needs based on the 1.3 W power dissipation specification.
