Digital Isolators are circuit components used to mitigate the process of electrical current passing between two systems, in order to prevent electric shock and other forms of potential danger. They are also often used in applications where radio frequency interference (RFI) could be an issue. A perfect example of a digital isolator is the SI8735BC-ISR.

The SI8735BC- ISR is a hysteresis-coupled isolated gate driver that comes in a surface mount 8-pin plastic package. It is an adjustable current-mode driver, designed to be used with a power MOSFET pass element. The features of the SI8735BC-ISR include low output offset voltage, low input offset voltage, fast slew rate, and high open-drain output voltage. It also offers superior over-current and under-voltage protection, as well as high-side short circuit protection. This makes it ideal for applications such as motor control, power management, and data communication.

The SI8735BC-ISR is especially useful in applications such as silicon switching where a controlled switching speed is desired in order to reduce power losses. In addition, its ability to provide a low leakage path of current during switched-off periods, as well as its simple circuit layout, also makes the SI8735BC-ISR extremely useful in cooling and thermoelectric (TE) applications where a regulated temperature is desired.

The main advantage of using the SI8735BC-ISR over other digital isolators is its powerful output stage. The output stage allows the device to offer a higher slew rate than other digital isolators, making it more suitable for applications which require switching speed. It can also sustain up to 30V of output voltage, making it suitable for higher current and voltage applications compared to other isolators.

The working principle of the SI8735BC-ISR is based on hysteresis-coupling. In a hysteresis-coupling circuit, the output of one device is used to modify the state of another. The current path between the two devices is limited due to the hysteresis effect created during the circuit\'s operation. Through the hysteresis-coupling circuit, the SI8735BC-ISR isolates a high-side load from the low-side of the circuit, thus providing an effective electrical isolation.

The SI8735BC-ISR can be used in a variety of applications including motor control, power management, and data communication. Its adjustable current-mode driver makes it an optimal choice for power-efficiency applications, and its high output voltage makes it suitable for applications that require a controlled switching speed. In addition, its low leakage path of current during switched-off periods and simple circuit layout make the SI8735BC-ISR an ideal choice for cooling and TE applications.
