The SI8220BD-A-IS Isolators - Gate Drivers are used to drive high-powered MOSFETS and IGBTs in electric motor control, propulsive or traction systems and other systems where signals must be kept isolated. It is used to isolate inputs and outputs and provide galvanic electrical isolation between circuits. This insulation offers protections against electrical shocks and current leakage. It also provides circuit-proofing of the system from dangerous surges, surges, lightning and other environmental disturbances.

These Isolators - Gate Drivers employ high-speed signal isolation technology, based on an isolated gate driver that ensures that the signal transmitted between the input and output is completely isolated and will not be affected by external electrical noise, static electricity and ground loop. The gate driver is a silicon band gap-integrated gate driver that has a voltage rating of 600 volts. This rating provides the driver with greater capability than traditional drivers, which usually require a much higher voltage rating to achieve the same level of performance. This makes the SI8220BD-A-IS Isolators - Gate Drivers an ideal choice for applications requiring high performance from a signal isolation driver.

The architecture of the SI8220BD-A-IS Isolators - Gate Drivers consists of two main parts: a power device and a signal isolator. The power device provides a supply voltage to the driver, and it is powered by a common power supply. This power device usually consists of a transistor, thyristor, MOSFET or IGBT, and it is responsible for providing the gate voltage needed to open or close the switching circuits. The signal isolator is connected to the power device and is responsible for providing isolated signal transmission between the input and output of the device. This isolation is achieved using optical or electrical techniques, depending on the particular device type.

The SI8220BD-A-IS Isolators - Gate Drivers are primarily used in applications where high voltage and high frequency signals are used, such as transformer, IGBT and MOSFET gate drivers, motor control systems and other power-protection and interface systems. They offer the highest level of performance, ensuring that the signals transmitted between the input and output circuits remain isolated and free from interference, spikes and other disturbances. The driver is also highly reliable, offering years of trouble-free operation.

The SI8220BD-A-IS Isolators - Gate Drivers are also used for a wide range of other applications, including interface applications, optocoupler circuits, electronic circuit protection, serial communication circuits and more. In these applications, the isolator can provide isolation between the input and output, as well as protection against current leakage. These devices are renowned for their reliability, accuracy and versatility, allowing them to be used in a variety of different applications.

The SI8220BD-A-IS Isolators - Gate Drivers have a number of advantages over conventional devices. They offer significantly higher levels of performance, reliability and accuracy, making them much more suited for high-performance applications. They also require very low power to operate, meaning that they can be used in portable devices. Finally, their isolated gate driver ensures that no current flows between the input and output, meaning that high-voltage signals remain completely isolated from the rest of the circuit.
