ADuM7223 Half-Bridge Driver

Isolated precision half-bridge driver from Analog Devices with a 4 A output

Image of Analog Devices' ADuM7223 Half-Bridge DriverThe ADuM7223 is a 4 A, isolated, half-bridge gate driver that employs Analog Devices, Inc.’s iCoupler® technology to provide independent and isolated high- and low-side outputs. Combining high-speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and non-isolated gate drivers. By integrating the isolator and driver in a single package, propagation delay is a maximum of only 60 ns and the propagation skew from channel to channel is a maximum of only 7 ns.

The ADuM7223 provides two independent isolation channels. The ADuM7223 operates with an input supply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. The outputs operate in a wide range from 4.5 V to 18 V with three output voltage versions available. The 5 x 5 mm, LGA package provides 2500 VDC peak operating voltage from input to output and from output to output.

In comparison to gate drivers employing high-voltage-level translation methodologies, these gate drivers offer the benefit of true galvanic isolation between the input and each output. As a result, these gate drivers provide reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.
