Overview
The NCP5109ADR2G, produced by onsemi, is a high-voltage gate driver IC designed to drive two N-channel power MOSFETs or IGBTs. This device is available in two versions: A and B, each catering to different configuration needs. Version A supports any high-side and low-side configuration, while Version B is specifically designed for half-bridge configurations with integrated cross-conduction protection. The NCP5109ADR2G uses the bootstrap technique to ensure proper drive of the high-side power switch, making it suitable for various power conversion applications.
