Digital Isolators

Digital isolators are electronic isolators which transfer digital electrical signals, while isolating an incident electrical circuit from any ground loops or other common-mode disturbances. This is accomplished by means of the digital isolator\'s one-way unidirectional electrical coupling between two isolated circuits, which is commonly referred to as galvanic isolation.

The SI88642EC-IS digital isolator is one of the newest editions of digital isolators from Silicon Labs. This device is designed to bridge the gaps between high performance analog data transfer and different control systems. With its compact size and low cost, this isolator will allow for a higher degree of accuracy and reliability in various applications.

Application Field

The SI88642EC-IS is designed to be used in industrial, medical, automotive, and consumer applications. Industrially, this isolator can be used in a wide range of power, motor, and other industrial control systems. Its isolation protection ensures that the operation of the device will continue to function even in harsh environments.

In terms of medical applications, this isolator can provide isolation protection in equipment such as ventilators, ECG machines, dialysis machines, portable medical instruments, and EMI/RFI filtering systems. It can also be used to ensure that medical equipment is compliant with applicable standards for safety isolation.

For automotive applications, the SI88642EC-IS can provide isolation protection between vehicles and their electronic control systems. This ensures that the vehicle\'s safety systems remain operational in the event of an electrical failure or disturbance.

In consumer applications, the SI88642EC-IS can be used to protect consumer electronics from over-voltage and over-current situations. This will ensure that the device\'s circuitry remains protected from these electrical transients.

Working Principle

The SI88642EC-IS digital isolator functions by transferring digital electrical signals, while isolating an incident electrical circuit from any ground loops or other common-mode disturbances. In this way, it prevents any direct electrical connection between the two electrical systems.

To accomplish this, the isolator employs a combination of insulated gate bipolar transistors (IGBTs) and optical diodes. The IGBTs are used to transfer the digital electrical signals between the two isolated circuits, while the optical diodes provide isolation between the two circuits.

In order to provide the required level of isolation, the device provides a low frequency (5 kHz to 200 kHz) isolation barrier between the two electrical systems. This barrier prevents any direct electrical connection between the two isolated circuits, which ensures that the operation of the device will continue to function even in the presence of noise or other external disturbances.

In addition, the SI88642EC-IS also achieves high levels of reliability and accuracy through its integrated error-correction and built-in data integrity mechanisms. These mechanisms ensure that any data transferred between the two circuits is accurate and up-to date.

Overall, the SI88642EC-IS digital isolator provides an effective and reliable method for transferring digital electrical signals between two isolated circuits, while ensuring that the operation of the device will continue to function even in the presence of noise or other external disturbances.
