ADUM7223ACCZ-RL7

The ADuM7223ACCZ-RL7 by Analog Devices Inc. is a precision, isolated half-bridge gate driver featuring 4.0A peak output current. It utilizes iCoupler® technology for independent and isolated high-side and low-side outputs, providing superior performance compared to traditional isolation methods.

This gate driver operates with an input supply voltage range of 3.0 V to 5.5 V and offers an output drive voltage from 4.5 V to 18 V. Key electrical specifications include a maximum propagation delay of 64 ns and channel-to-channel matching of 8.5 ns. It supports high-frequency operation up to 1 MHz and boasts high common-mode transient immunity of over 25 kV/µs.

The device is housed in a compact 5 mm x 5 mm, 13-terminal LGA package. It provides a working voltage of 565 V peak from input to output and 700 V peak from output to output, ensuring robust isolation for demanding applications. The high junction temperature operation up to 125°C makes it suitable for challenging environments.

Applications for the ADuM7223ACCZ-RL7 include switching power supplies, isolated IGBT/MOSFET gate drives, and industrial inverters. Its true galvanic isolation ensures reliable control over switching characteristics in IGBT/MOSFET configurations.
