NCP5106APG

Overview

The NCP5106APG is a high-voltage gate driver IC designed for direct drive of two N-channel power MOSFETs or IGBTs in high-side and low-side configurations. It features a bootstrap technique for high-side switching, independent logic inputs, and a wide supply voltage range from 10V to 20V. The device provides source/sink currents of 250mA/500mA with propagation delay matching between channels. It includes undervoltage lockout (UVLO) for both channels and supports 3.3V and 5V input logic levels.

Feature Summary

• Supports high-side and low-side configurations for driving N-channel power MOSFETs or IGBTs
• Features independent logic inputs compatible with 3.3V and 5V control circuits
• Includes undervoltage lockout protection on both output channels

Applications

• High-side and low-side power converter topologies
• Complementary drive converters such as asymmetric half-bridge designs
• Active clamp flyback converters

Procurement Notes

Verify the specific package type and suffix against official documentation, as the NCP5106 series utilizes various suffixes to denote different packaging options. Confirm availability status directly with authorized distributors, as this component may be subject to end-of-life notices or limited stock conditions. Ensure that the selected variant matches the required thermal and electrical specifications for the target application.

Selection Notes

Select the NCP5106APG when a high-side and low-side configuration is required rather than a standard half-bridge setup. This version offers independent logic inputs suitable for diverse circuit topologies. Consider the 600V high-voltage rating and dV/dt immunity when designing for industrial power supplies or motor drives where fast voltage transients are present.

Part Context

The NCP5106APG belongs to the NCP5106 family of high-voltage gate drivers manufactured by onsemi. This series is engineered for robust performance in demanding power electronics applications. The 'A' designation specifically indicates the high-side and low-side configuration variant, distinguishing it from the 'B' version which is optimized for half-bridge applications with internal dead-time control.
