NCP302155MNTWG

Overview

The NCP302155MNTWG is an integrated driver and MOSFET component manufactured by onsemi. It combines a high-side MOSFET, a low-side MOSFET, and a gate driver within a single package. The device supports an average current of up to 55 A and operates with switching frequencies up to 2 MHz. It features compatibility with 3.3 V or 5 V PWM inputs and includes internal bootstrap diodes. The unit provides thermal warning outputs and thermal shutdown protection.

Feature Summary

Integrates high-side and low-side MOSFETs with a dedicated driver in one package
Supports switching frequencies up to 2 MHz for high-speed applications
Includes internal bootstrap diode for simplified circuit design
Provides thermal warning output and thermal shutdown protection

Applications

Desktop and notebook microprocessor V-Core DC-DC converters
Non-V-core DC-DC converters for workstations and servers
High-current DC-DC load point converters
Small voltage regulator modules

Procurement Notes

Verify the specific suffix MNTWG against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure that the thermal management requirements align with the device's power dissipation capabilities. Confirm that the input signal levels match the specified 3.3 V or 5 V PWM compatibility before finalizing procurement.

Selection Notes

Select this component when board space is limited and high current density is required. It is suitable for applications needing fast switching speeds up to 2 MHz. Consider the integrated nature of the driver and MOSFETs to reduce parasitic effects compared to discrete solutions. Verify that the target application falls within the supported thermal operating range.

Part Context

This part belongs to the NCP302155 series of integrated drivers and MOSFETs from onsemi. These devices are designed to optimize performance for high-current DC-DC buck power conversion applications. The integration aims to lower package parasitics and reduce overall footprint compared to traditional discrete implementations.
