Analog Devices ADuM7223 Half-Bridge Driver

Analog Devices ADuM7223 Half-Bridge Drivers

Analog Devices' ADuM7223 is a 4.0A isolated, half-bridge gate driver designed using Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, these isolation components offer outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and non-isolated gate drivers.

Featuring two independent isolation channels, ADuM7223 operates with an input supply ranging from 3.0V to 5.5V, providing compatibility with lower voltage systems. The outputs operate in a wide range from 4.5V to 18V with three output voltage versions available. The 5mm × 5mm, LGA package provides 565V operating voltage from input to output and 700V from output to output. By integrating the isolator and driver in a single package, propagation delay is a maximum of only 64ns, and the propagation skew from channel to channel is a maximum of only 12ns at 12V. Compared to gate drivers using high voltage level translation methodologies.

ADuM7223 offers the benefit of true, galvanic isolation between the input and each output. As a result, this gate driver provides reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.
