Overview
The NCP5106BMNTWG is a high voltage gate driver IC produced by onsemi. This device is designed to provide two outputs for the direct drive of two N-channel power MOSFETs or IGBTs, typically arranged in a half-bridge configuration or other high-side and low-side configurations. The NCP5106 utilizes the bootstrap technique to ensure proper drive of the high-side power switch and features independent logic inputs to accommodate various topologies.
