NCV303150MTW

Overview

The NCV303150MTW is an integrated gate driver and MOSFET component from onsemi, combining a high-side MOSFET, a low-side MOSFET, and a dedicated driver within a single PQFN-31 package. Designed for high-current DC-DC buck power conversion applications, it features 30V breakdown voltage MOSFETs capable of handling up to 50A average current with switching frequencies reaching 1MHz. The device supports 3.3V or 5V PWM inputs and includes precise current monitoring with zero-cross detection options. It integrates internal bootstrap diodes, thermal marking under over-temperature conditions, over-current protection, and undervoltage lockout for VCC and PVCC rails.

Feature Summary

• Integrates high-side and low-side MOSFETs with a dedicated driver in a compact copper clip PQFN package to minimize parasitic effects
• Provides precise current monitoring with zero-cross detection capabilities for accurate load management
• Includes comprehensive protection mechanisms such as over-temperature thermal marking, over-current protection, and undervoltage lockout

Applications

• High-current DC-DC buck power conversion systems
• Point-of-load (POL) converter modules
• Server and workstation VRM designs

Procurement Notes

Verify the complete part number including the suffix 'MTW' to ensure correct packaging and tape/reel specifications. Confirm that the automotive grade designation 'NCV' aligns with your project's reliability requirements. Cross-reference the datasheet for specific thermal pad dimensions and soldering profiles compatible with the PQFN-31 package to ensure proper assembly and heat dissipation performance.

Selection Notes

Select this component when space constraints and efficiency are critical for high-current buck converters. The integrated solution reduces board area compared to discrete drivers and MOSFETs. Ensure the input PWM signal levels match the 3.3V or 5V compatibility. Evaluate the thermal performance requirements against the 50A average current capability and the package's thermal resistance characteristics for your specific ambient conditions.

Part Context

This part belongs to onsemi's NCP303150 series of integrated drivers and MOSFETs. The 'NCV' prefix indicates it is qualified for automotive applications, meeting stricter reliability standards than standard commercial parts. It is part of a family designed to simplify power stage design by merging control logic and power switches into a single optimized package.

Replacement Considerations

Direct substitutes include other variants within the NCP303150 series, such as the NCP303150AMNTBG or NCP303150MNTWG, provided they meet the same electrical and thermal specifications. Verify pin-to-pin compatibility and package dimensions before substitution.
