Overview
The NCP5106BDR2G, produced by onsemi, is a high voltage gate driver IC designed to drive two N-channel power MOSFETs or IGBTs. This component is particularly useful in configurations such as half-bridge, full-bridge, and other complementary drive converters. It employs the bootstrap technique to ensure proper drive of the high-side power switch and features independent logic inputs to accommodate various topologies.
