ST3485EIYDT

ST3485EIYDT is an advanced, low power, galvanically isolated, 4-channel, full-duplex transceiver which combines a serial interface link controller, forward error correction engine, 3.3 V to 5 V transformer-coupled transceivers, a 5 V power supply regulator, and a 5 V power supply for providing power for digital I/Os. This transceiver is designed for digital communication in industrial, automotive, and medical applications.

This device is suitable for applications that require robust digital communication such as high temperature and extended voltage range systems. It also integrates an integrated DC-DC converter to provide an external 5 V supply for device power supply and additional 3.3 V downstream operation of digital I/Os.

The working principle of ST3485EIYDT is based on the use of galvanic isolation technology. This technology provides effective separation between two systems that are connected by the device. It eliminates any potential common mode currents between the two systems, which prevents damage to the system due to EMI/RFI interference. By using galvanic isolation, the device can guarantee reliable communication between two circuits as well as low power consumption.

ST3485EIYDT is mainly used in the industrial, automotive and medical fields. It is used in a variety of applications such as smart healthcare, robotics and factory automation, programmable logic controllers, motion controllers, and embedded systems. In industrial applications, it is often used to provide robust communication between a Programmable Logic Controller (PLC) and a Human Machine Interface (HMI). In automotive applications, it is used for communication between a car’s main body control unit and other vehicle systems such as collision detection or safety features. In medical applications, the device is used for communication between patient monitoring systems and other medical devices.

The ST3485EIYDT combines a serial interface link controller that is compliant to the universal asynchronous receiver/transmitter (UART) protocol, 4 full-duplex, digitally isolated, 3.3 V to 5 V transformer-coupled transceivers, and a 5 V power supply regulator. The serial interface link controller is a high-speed, edge-triggered transceiver with a maximum data rate of 5 Mbps that is compliant to the UART protocol. The transceivers provide rate matching and data transmission rate conversion, allowing data to be received at rates up to 76.8 Kbps. The transceivers are are also designed for low power consumption and are tolerant of noise and electromagnetic interference.

The 5 V power supply regulator provides power for the digital I/Os and is configurable to deliver up to 1 A with a minimum input voltage of 3.3 V, allowing the device to be used with a wide range of power supplies. The 5 V power supply is also used to provide power for the DC-DC converter, allowing the device to be powered without the need for an external DC-DC converter.
