MAX14937AWE+

Digital Isolators provide isolation between two communication links, normally digital or electrical. They offer a degree of protection between two circuits where galvanic isolation is desired and also provide a much higher degree of protection than what can be achieved from common opto-couplers. The MAX14937AWE+ application field and working principle Explained in this article make use of their isolation abilities in a variety of ways.

The MAX14937AWE+ digital isolator is a 16-channel, bi-directional digital isolator used to transfer digital signals, such as I2C, SPI and SMBus safely between two isolated circuits. The MAX14937AWE+ digital isolator features a robust isolated-channel design, which consists of two shielded inductors, one on the input side and the other on the output side. This shielded inductor creates a Faraday shield, which acts as an electrical barrier, preventing any voltage transients or ground loops from affecting the data being transferred between two circuits.

The MAX14937AWE+ provides flexible I/O options. It can be configured to support either 3.3V or 24V I/O voltages and its 16 channels can be independently enabled and disabled in real-time. In addition, an external isolated power supply is also available for specialized applications.

The working principle of the MAX14937AWE+ is based on a patented signal-sharing architecture. Signals received at the input of one channel will be shared with the other 15 channels. The data being transmitted is isolated between the two circuits, which provides a high level of protection from ground-loops and corrupted data. The data is also transmitted over a robust shielded inductor, which prevents any voltage transients or ground-loops from affecting the data being transferred.

The MAX14937AWE+ is a flexible digital isolator suitable for a wide variety of applications. It is suitable for industrial automation, automotive, medical, and consumer electronics, and provides a high level of isolation between two circuits for safe data transfer. The MAX14937AWE+ is a reliable and cost-effective solution for those requiring a reliable and secure source of isolated data.
