NCP303150DMNTWG

Overview

The NCP303150DMNTWG is an integrated gate driver and MOSFET device from onsemi, combining a high-side driver, low-side driver, and power MOSFETs in a single package. It features a 39-pin PQFN (5 mm x 6 mm) copper clip package. The device supports a supply voltage range of 4.5 V to 5.5 V and delivers an output current of 50 A. Switching characteristics include a rise time of 17 ns and a fall time of 26 ns. It operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Integrates high-side and low-side drivers with dual MOSFETs for compact design
• Includes integrated current monitor with zero-cross detection options
• Features internal bootstrap diode and support for Intel Power State 4

Applications

• High-current DC-DC buck power conversion
• Server and workstation VRM designs
• Graphics card power delivery systems

Procurement Notes

Verify the End-of-Life status before procurement, as this component is subject to discontinuation by the manufacturer. Confirm that the specific DMNTWG suffix matches the required tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints and thermal management requirements for the 39-pin PQFN package.

Selection Notes

Select this component for applications requiring high average current handling up to 50 A and switching frequencies up to 1 MHz. It is suitable for designs needing precise current monitoring and protection features such as overcurrent and overtemperature detection. Consider the integrated solution benefits over discrete components to reduce parasitic effects and board space.

Part Context

This part belongs to the NCP30315x series of integrated drivers and MOSFETs. It is designed to replace discrete high-side and low-side driver combinations, offering optimized performance for power management ICs. The series targets high-efficiency power conversion applications where size and reliability are critical constraints.

Replacement Considerations

Check for official substitute part numbers from onsemi or compatible alternatives with matching pinout and electrical specifications. Verify thermal resistance and package dimensions if considering cross-manufacturer replacements.
