IL3585 is an integrated digital isolator designed to address challenges of galvanic isolation. It allows information to be transferred between two units of a system without any direct electrical connection. As a digital isolator, IL3585 is made up of a transmitter driver on the input side and a receiver on the output side. Compared with traditional analog isolation solutions, IL3585 offers the advantage of higher reliability and longer life due to its galvanic isolation between two units of the system.

In terms of application fields, IL3585 can be widely applied to motors and motion control, medical devices and equipment, industrial process control, railway transportation, power monitoring and security, as well as solar, wind and electric vehicle fields. It provides reliable isolation in the data transmission between motors and motion controllers, and among medical equipment and instrumentation. With its high isolation voltage and faster response time, IL3585 can also serve in applications in industrial process control to provide isolation of data and command signals. Its low power consumption and high noise immunity make it the ideal choice for railroad and power monitoring.

The working principle of IL3585 can be broken down into three elements: the transmitter side, the receiver side and the coupled transformer. The isolator features a 6-pin components that includes two buses, a bus-bypass switch, and a transmitting control sense module on the transmitter side. On the receiver side, there are two logic inputs and a device enable signal pin. In the middle of the isolator is a coupled transformer which functions to transfer signals over the air gap without any physical connection.

In a nutshell, the working principle of IL3585 is basically that signals from the transmitting side will be deterred by the driver, amplified and transferred by the coupled transformer to the receiver side. The logic inputs on the receiver side will then receive and process the signal, and the device enable signal will turn on the receiver and start the subsequent process. Finally, the output will be generated on the receiving side according to the processed signal.

In conclusion, IL3585 is a digital isolator that effectively isolates interferences and noises between two systems. Its application fields cover a large range of fields, while its working principle allows information to be transferred easily between two systems without direct electrical contact. Therefore, IL3585 is a better and more reliable solution compared to analog isolation solutions.
