MP1917AGR-P

Overview

The MP1917AGR-P is a high-frequency half-bridge gate driver manufactured by Monolithic Power Systems. It features dual drivers with two outputs and delivers a peak output current of 4 A. The device operates within a supply voltage range of 8 V to 15 V. It exhibits fast switching characteristics, with rise and fall times of 15 ns and 12 ns respectively. The component supports surface mount installation in a QFN package and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates dual high-speed half-bridge drivers for efficient power stage control
• Provides robust 4 A peak output current capability for driving MOSFETs or IGBTs
• Supports high-frequency operation with minimal propagation delay and switching transitions

Applications

• Motor drive systems requiring precise half-bridge control
• High-frequency DC-DC converter topologies
• Inverter circuits for power conversion applications

Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with your PCB footprint and thermal requirements. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement. Ensure that the operating voltage and current ratings align with your system design constraints to prevent device failure.

Selection Notes

Select this component when designing circuits that require a dedicated half-bridge driver with high peak current capability. Consider the 15 V maximum supply voltage limit and the -40°C to +125°C operating temperature range. Evaluate the 4 A output current against the gate charge requirements of your target power switches to ensure adequate drive strength.

Part Context

This part belongs to the MPS gate driver family, specifically designed for half-bridge configurations. It falls under the PMIC category and is distinct from single-ended or full-bridge drivers. The MP1917AGR-P is engineered for applications demanding fast switching speeds and reliable performance in industrial and automotive environments.

Replacement Considerations

Consult the official MPS replacement guide for verified cross-reference part numbers. Do not assume functional equivalence with other half-bridge drivers without verifying pinout, voltage ratings, and timing specifications.
