ADuM4221/-1/-2/W Half-Bridge Gate Driver

Analog Devices' family of isolated, half-bridge gate drivers with adjustable dead time and 4 A output provide reliable control over the switching characteristics of the insulated gate bipolar transistor (IGBT)/metal-oxide semiconductor field effect transistor (MOSFET) and silicon carbide (SiC) configurations.

The ADuM422x driver family comprises a variety of options including the ADuM4221 dual input option with dead time, the ADuM4221-1 single input option with dead time, the ADuM4221-2 dual input option with no dead time, and the ADuM4221W automotive-qualified dual input option with dead time.

Features

• Dual-channel gate driver with adjustable dead time to improve overall efficiency
• Robust OOK architecture provides excellent CMTI for use with newer high-performance applications such as GaN and SiC switch technologies
• High drive strength and low delay for highest performance applications; 45 ns prop delay, 10 ns channel-to-channel skew; superior timing performance stability reduces voltage distortion and harmonics, providing better lifetime, and output drive strength allows faster switching of devices
