NCP5106BMNTWG

Overview

The NCP5106BMNTWG is a high-voltage half-bridge gate driver IC manufactured by onsemi, designed for direct drive of two N-channel power MOSFETs or IGBTs. It operates with a bootstrap voltage up to 600 V and supports a supply voltage range of 10 V to 20 V. The device features independent non-inverting inputs, peak output currents of 250 mA source and 500 mA sink, and typical rise/fall times of 85 ns and 35 ns respectively. It includes internal fixed dead-time for cross-conduction protection, UVLO, and dV/dt immunity of ±50 V/ns. Packaged in a 10-DFN (4x4) surface-mount format, it functions within a junction temperature range of -40°C to 125°C.

Feature Summary

• Integrated half-bridge configuration with internal fixed dead-time to prevent cross-conduction
• High voltage capability supporting bootstrap operation up to 600 V
• Robust dV/dt immunity ensuring stable performance during rapid voltage transitions
• Independent logic inputs compatible with standard control interfaces

Applications

• Half-bridge power converters
• Complementary drive converters such as asymmetric half-bridge and active clamp topologies
• Electronic ballasts for lighting applications

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm package marking and datasheet revision against original specifications. Check for RoHS compliance documentation. Validate lead frame material and pin alignment. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component for designs requiring isolated high-side driving without external isolation barriers. Suitable for applications needing precise timing synchronization between high and low side switches. Consider thermal management requirements for the DFN package. Verify input logic levels match controller outputs. Evaluate system voltage stress against the 600 V rating.

Part Context

Part of the NCP5106 family including version A for full-bridge/high-low configurations. Shares core driver architecture with optimized half-bridge specific features. Designed for industrial power conversion and motor drive systems. Replaces older discrete driver solutions with integrated protection features.

Replacement Considerations

NCP5106AMNTWG offers similar electrical characteristics but lacks internal dead-time generation, requiring external timing control for half-bridge applications.
