This document provides information about the ADuM7234 isolated precision half-bridge driver. The driver features isolated high-side and low-side outputs, high frequency operation, high temperature operation, and high common-mode transient immunity. It is suitable for applications such as isolated IGBT/MOSFET gate drives, plasma displays, industrial inverters, and switching power supplies.
The ADuM7234 is an isolated, half‑bridge gate driver that uses Analog Devices' Coupler™ technology to provide independent high‑side and low‑side outputs with galvanic isolation. It supports up to 4 A peak output current and a differential voltage of 350 V peak, making it suitable for IGBT/MOSFET gate drives in industrial inverters, switching power supplies, and plasma displays.
The document includes full electrical characteristics, package data, insulation and safety specifications, recommended operating conditions, pin descriptions, and typical performance graphs. It also provides regulatory information and application guidance for designers.
