It is designed to be used with a range of current values, from 10 to 20A and offers low on resistance. It also has an isolation rating of 3,000 Vrms, making it suitable for applications that require high voltage isolation.

Application Fields

The SI8235AB-D-IS1 is a versatile device, commonly employed in a wide range of applications that require gate-level or low-level signal isolation. Some common applications for the SI8235AB-D-IS1 include:

• Automatic balancing systems
• Power supplies
• Induction heating
• Converter and variable frequency drives
• Array controllers
• Motor controllers
• DC Motors
• Servo systems

In each of these applications, the SI8235AB-D-IS1 isolator solves the problem of unreliable, low signal, and high voltage isolation. It provides galvanic isolation between low-level switching signals and gate-level outputs while still providing a high current.

Working Principle

The working principle of the SI8235AB-D-IS1 is based on the fact that it provides galvanic isolation between the switching signals and the gate outputs. This is achieved using an internal optocoupler that acts as a non-contact connection between the input and the output. When a low-level signal is applied at the input, the optocoupler is activated, which in turn activates a switch inside the SI8235AB-D-IS1, allowing the current to flow to the output. This current flow is then isolated from the input signal, providing a high degree of voltage isolation.

Conclusion

The SI8235AB-D-IS1 isolator is a versatile device that can be utilized in a variety of applications requiring gate-level or low-level signal isolation. It provides high voltage isolation and is designed with a wide range of current values, which makes it suitable for a number of applications. The working principle of the SI8235AB-D-IS1 is based on the use of an internal optocoupler, which provides the necessary galvanic isolation between the input and output signals.
