The SI8273GBD-IS1 is an isolated RS-485/RS-422 transceiver with integrated power and signal isolation. It is designed to provide power a maximum of 3kV in any single direction and has a wide range of applications in various fields.

Isolators are components that provide galvanic isolation between electronic circuits and enable electrical signals to pass between them with low distortion. They are widely used in various harsh environments, like industrial, automotive and medical, where signal distortion due to external electrical noise must be prevented. Gate drivers are components that enable larger currents to be driven and higher voltages to be switched in higher-power applications. As such, they are often used in applications such as switching motors and actuators, power supplies and power converters.

The SI8273GBD-IS1 provides an isolation barrier between the RS-485/RS-422 transceiver and the application board. It takes advantage of Silicon Labs’ advanced isolation technology and utilizes integrated power and signal isolation to ensure interference-free signal transfer. The SI8273GBD-IS1 is a high-efficiency pass and isolate logic isolator with low thermal resistance. It operates on a wide voltage range from 6V to 32V and has a integrated driver with three level of logic signal isolation.

The working principle of SI8273GBD-IS1 lays in the use of the Avalanche Voltage Block (AVB). It is an isolation technique based on the use of avalanche breakdown of an insulator under an electric field to achieve an effective electric insulation between two circuits. The insulation voltage of electric field is typically higher than 10kV/mm and thus enables the isolation between the circuits. As per application case the signal to be isolated will pass through the AVB and the analog and isolated digital signal will be driven into the application board.

The SI8273GBD-IS1 mainly operates in two-level logic control systems, also referred to as the ‘double-peak control’. In this system, the logic level is divided into two parts. A logic ‘1’ is indicated by a high level and a logic ‘0’ by a low-level. The two level logic control allows the motor to be accurately controlled or the signal to be accurately transmitted, which makes it suitable for a variety of applications. For instance, it can be used in automotive applications, industrial environments, and ‘smart’ home applications.

The SI8273GBD-IS1 provides a maximum data rate of up to 12Mb/s and a maximum data rate of up to 2Mb/s in RS-485/RS-422 communication mode. It also features built-in under-voltage, over-voltage and thermal shut-down protection. Furthermore, it allows for regulated supply voltage and currents settings and has a low power consumption. In short, the SI8273GBD-IS1 provides unique advantages and flexibility when used in various industrial and automotive applications.

SI8273GBD-IS1 is a cost-effective solution for isolating RS-485/RS-422 transceivers and enabling a reliable and low distortion transmission. It is a perfect choice for applications with high-powered components, where signal distortion due to electrical noise must be prevented. This high-efficiency isolator offers integrated power and signal isolation with a wide range of operational voltages, making it an ideal choice for automotive, industrial, and home applications.
