Isolators - Gate Drivers are devices used to protect sensitive control systems from high voltage AC or DC power grids, and to provide a reliable electrical isolation barrier between the two. ADUM7234BRZ is an isolator designed specifically for gate driving applications in industrial motor control and power electronics.

The ADUM7234BRZ is designed for the typical gate driving applications of two power semiconductors such as isolated MOSFETs and IGBTs used in motor control, motor power supplies, and related power management applications. It offers two independent 4-channel channels, both delivering up to 12 mA of peak drive current for driving MOSFETs. Its channels can be used together to provide higher current to drive large MOSFETs or higher voltage gate drive applications.

The ADUM7234BRZ also features bidirectional isolation to provide a galvanic isolation barrier of up to 2450 Vrms and 20 dB of common-mode noise rejection, making it well-suited for protection from high voltage AC power grids.

This device also provides tight matching of power-on delays and turn-off times, so that the turn-off time of one channel is proportional to its turn-on time. Additionally, it features a built-in fault protection circuit, which disables the output of the part in case of a fault, such as overcurrent protection, undervoltage lock-out, overtemperature protection and overvoltage protection.

The ADUM7234BRZ is an excellent choice for gate drive applications and offers high-performance, reliable operation. It provides a reliable electrical isolation barrier to protect a system\'s control systems from high voltage AC and DC power grids. Its built-in safety features also provide dependable protection against adverse conditions. This device provides superior immunity against EMF (electromagnetic fields) and is also UL approved.
