ADUM4221CRIZ

ADUM4221 is an isolated, half bridge gate driver. It employ Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side output. This isolator operate with a logic input voltage ranging from 2.5V to 6.5V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the device offer the benefit of true, galvanic isolation between the input and each output. The device have built in overlap protection and allow dead time adjustment. A single resistor between the dead time pin (DT) and the GND1 pin sets the dead time on the secondary side between the high-side and the low-side outputs. It is widely used in application such as switching power supplies, isolated IGBT/MOSFET gate drives, industrial inverters, gallium nitride (GaN)/silicon carbide (SiC) compatible etc.
