MP1922GV-Z

Overview

The MP1922GV-Z is a single-channel, half-bridge pre-driver IC from Monolithic Power Systems. It supports 100V operation with integrated current sense amplification and an internal charge pump for high-side gate drive. The device features non-inverting input logic and operates within a junction temperature range of -40°C to 165°C. It utilizes a QFN-22 surface-mount package suitable for compact motor control designs.

Feature Summary

• Integrated current sense amplifier for direct motor current monitoring
• Internal charge pump with auto-refresh capability for reliable high-side driving
• Supports 100V system voltage for robust power stage interfacing

Applications

• Motor driver applications
• Power control systems requiring half-bridge topology
• Industrial motor control units

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status as per manufacturer documentation. Confirm the QFN-22 package dimensions against PCB footprint requirements. Ensure thermal management strategies align with the specified 165°C maximum junction temperature limit during operation.

Selection Notes

Select this component when a single-channel half-bridge solution with integrated sensing is required. The internal charge pump simplifies bootstrap circuit design compared to discrete drivers. Consider the 3A source and 4A sink currents for driving external MOSFETs in medium-power motor applications.

Part Context

This part belongs to the MP1922 series of half-bridge pre-drivers designed for motor control. It integrates functions typically requiring multiple discrete components, reducing board space. The series targets applications needing reliable high-voltage gate driving with simplified external component counts.

Replacement Considerations

Check datasheet compatibility for pin-to-pin replacements within the MP1922 family. Verify if alternative suffixes like 'P' offer identical electrical characteristics or different packaging options.
