Digital isolators (DI), also known as integrated isolators, are electronic devices used to electrically isolate one section of a circuit from another, while maintaining the same level of electronic performance. The isolator is commonly used in the construction of high-end specialized systems with complex requirements for power, temperature, switching times, and other operational parameters. SI88241BC-IS is one such digital isolator.

The SI88241BC-IS is designed to extend system live by protecting the driver IC from overvoltage, ESD and EMI. It is a Bi-CMOS-based open-drain device with high-side and low-side transistors that can be operated with a supply voltages ranging from 9 volts to 24 volts. It also comes with an integrated ESD protection diode that eliminates the need for external ESD protection components. This makes it ideal for applications such as medical equipment, consumer electronics and communications systems which are sensitive to ESD and EMI.

The integrated isolator has a wide range of features, including a supply voltage and over-current protection that can be easily configured, and adjustable power-on-off delay times. It also has an adjustable pull-up resistor which can be controlled either by the host controller or with an external resistor network. This makes it easy to tailor the device for a particular power requirement. The wide range of features makes the SI88241BC-IS an ideal choice for designs with short time to market constraints.

The SI88241BC-IS has two main elements; a voltage regulator and an isolated driver. The power-line voltage regulator provides a stabilized voltage to the integrated driver, protecting against power line induced interference. The isolated driver then operates at the same voltage as the regulator, thus providing the necessary isolation from the other parts of the circuit.

The SI88241BC-IS is designed for current protection and noise immunity, two of the key applications that a digital isolator is used for. It offers a low dropout and low on-resistance device that can be used in both portable and stationary applications. This makes it ideal for portable and fixed-voltage applications in industrial electric systems. It also offers a high-side-to-low-side control scheme, allowing for isolation from interference between the two sets of circuits.

The SI88241BC-IS is an ideal choice for applications that require a highly reliable digital isolator. It offers low standby current and low on-resistance operation as well as extended protection against ESD and EMI. Its flexible configuration options make it simple to customize for different designs, allowing for quick time-to-market requirements. Additionally, the wide range of features offered ensure it can be used in many different applications.
