The ADUM6132ARWZ is an isolator series member of the Analog Devices iCoupler® family of digital isolators. This digital isolator uses chip scale micro-transformers to provide up to 2000 Vrms of galvanic isolation for applications that deal with level shifters, data translation from a long differential bus, power management and signal conditioning. The ADUM6132ARWZ is a widely-applicable device that is beneficial in any system that requires reliable and cost-effective isolation with low power.

As an isolator, the ADUM6132ARWZ is designed to isolate the signals from its input to output pins. It provides an isolated gate driver with two isolated power rails (VCCIO1 low and VCCIO2 high), two isolated input signal pins (IO1 and IO2), and two isolated output signal pins ( Output1 and Output2) that can be used to drive the load. The device works with TTL, LVCMOS, and LVDS signals levels and offers data transmission rates from 1 Mbps to 500 Mbps, with galvanic isolation up to 2000 Vrms and isolation capacitance ranges from 0.1 pF to 3.5 pF.

The main application fields of ADUM6132ARWZ include level shifting, data translation, data forwarding, bus transceivers, and signal conditioning. It is mainly used in battery-operated systems and systems involving motor control, medical equipment, and other high-speed communications applications. The ADUM6132ARWZ also offers protection against EMC and ESD, as well as over-voltage and over-current conditions.

The working principle of the ADUM6132ARWZ is based on the use of Micro transformer technology for isolation. Each device consists of three transformer cores, two of which are used to drive the isolation barrier. The transformer cores are wrapped around a high-frequency switching power supply that provides the Vccio and Vcc3 voltage levels that power the device and activate the micro-transformers. When different voltages are applied to the two halves of the isolation barrier, an input signal on one side of the barrier causes a corresponding output signal on the other. Through the two small coils, the coils in the transformer create an inductive loop on the primary side, and the second loop is established on the secondary side. In this way, isolation is established between input and output signals.

The ADUM6132ARWZ isolator provides a wide range of benefits for users with its high efficiency, low power, and reliability. It is a highly useful isolator in a variety of applications, such as level shifting, power management, signal conditioning, bus transceiving, and data translation. It enables efficient data transmission up to 500 Mbps with up to 2000 Vrms of galvanic isolation and it also offers protection against EMC, ESD, and over-voltage conditions. This ensures that it can be used in a wide range of applications and systems.
