The ADuM1233 is a precision half-bridge driver from Analog Devices that uses the Analog Devices iCoupler® technology to provide independent and isolated high-side and low-side outputs. The device provides 0.1A peak output current and can operate at a maximum frequency of 5MHz. The ADuM1233 is widely used in isolated IGBT/MOSFET gate drives, plasma displays, industrial inverters, and switching power supplies.
The ADuM1233 is an isolated, precision half‑bridge gate driver that uses Analog Devices’ iCoupler technology to provide independent high‑side and low‑side outputs with up to ±700 V isolation. It replaces optocoupler‑based solutions, offering high‑speed operation up to 5 MHz and robust common‑mode transient immunity.
The document includes a functional block diagram, pin‑out descriptions, electrical characteristics, recommended operating conditions, and typical performance graphs. Safety and regulatory information such as UL1577 compliance and insulation ratings are also provided, making it a complete reference for designers of industrial inverters, switching power supplies, and IGBT/MOSFET gate‑drive applications.
