NCP5106AMNTWG

Overview

The NCP5106AMNTWG is a high-voltage gate driver IC designed for direct driving of two N-channel power MOSFETs or IGBTs. It supports half-bridge and full-bridge configurations with independent logic inputs. The device utilizes bootstrap technology for high-side switching and features a supply voltage range of 10V to 20V. Peak output currents are 250mA source and 500mA sink. It operates within a junction temperature range of -40°C to 125°C and is housed in a 10-DFN (4x4) package.

Feature Summary

• Supports half-bridge and full-bridge topologies with independent high-side and low-side inputs
• Provides dV/dt immunity to ensure stable operation during rapid voltage transitions
• Includes internal fixed dead-time control to prevent cross-conduction in bridge circuits
• Features under-voltage lockout (UVLO) on both channels for circuit protection

Applications

• Half-bridge power converters
• Complementary drive converters such as asymmetric half-bridge designs
• Active clamp converter topologies
• Industrial motor drive systems

Procurement Notes

Verify component authenticity through authorized distribution channels due to the presence of obsolete status indicators in public records. Confirm RoHS compliance and REACH material declarations prior to integration. Ensure that the 10-DFN footprint matches the target PCB layout specifications exactly. Validate thermal performance requirements against the specified junction temperature limits before finalizing the design.

Selection Notes

Select this component when designing high-voltage applications requiring independent control of high-side and low-side switches. It is suitable for systems needing robust dV/dt immunity and integrated cross-conduction protection. Consider the 10-DFN package constraints and the specific requirement for N-channel devices. Verify that the input logic levels align with the controller's output capabilities.

Part Context

This part belongs to the NCP5106 family of high-voltage gate drivers from onsemi. The 'A' suffix denotes the version with independent logic inputs, distinguishing it from the 'B' variant which integrates fixed dead-time. The family is engineered for driving N-channel MOSFETs and IGBTs in demanding power electronics environments.

Replacement Considerations

Public documentation indicates an End-of-Life (EOL) notice dated October 1, 2021. Designers should evaluate alternative high-voltage gate drivers with similar pinouts and electrical characteristics. Verify compatibility with existing PCB footprints and thermal management solutions when transitioning to successor components.
