ISO150AU/1K

Digital isolators are commonly used in applications where two electronic circuits need to communicate, but where direct electrical connection would cause damage or performance degradation due to uneven ground potentials or shielding issues. The ISO150AU/1K digital isolator is a perfect example of this type of device.

Applications

ISO150AU/1K digital isolators are primarily used in medical, industrial automation and commercial applications. In the medical field, they are often used in equipment such as ventilators, respirators, infusion pumps, and patient monitors, where a galvanic isolation of the control system from the sensing system is highly recommended. They are also used in laser drills and medical imaging equipment. In industrial automation applications, ISO150AU/1K digital isolators can be used to isolate the communications interface, allowing reliable communication between automated machinery. And in commercial applications, these isolators can be used in 5G network deployments, telecom base stations, power supply units, and other devices where a communication interface between two circuits is required.

Working Principle

A digital isolator is composed of two parts – a driver part that is situated at one end of the digital isolator and a receiver part at the other. The driver part is responsible for providing the voltage signal that is transmitted across the isolation barrier. The receiver part then converts the signal back into the original digital signal. The communication between the two parts of the isolator is done through the use of an isolation barrier; this provides galvanic isolation between the two electronic systems. The ISO150AU/1K digital isolator also utilizes a linear transformer driver (LTD) technology to reduce the power consumption of the isolator while ensuring a high level of accuracy.

The ISO150AU/1K digital isolator is designed to provide digital isolation and data transmission up to 1,000Vrms from Primary to Secondary side for one channel. It operates at a supply voltage of 5V and a transmission rate of 40MHz. The device is also designed to provide a 100% channel-to-channel data transmission for unidirectional communication. The digital isolator also features low power consumption, a wide ambient operating temperature range, high EMC performance, and RoHS compliant packaging.

Conclusion

The ISO150AU/1K digital isolator is a versatile and reliable device that can be used in a variety of applications. In medical, industrial automation, and commercial applications, it offers a reliable and cost-effective way to provide galvanic isolation between two circuits. The device features low power consumption, wide temperature range of operation, and high EMC performance. Thus, it is a perfect choice for many applications where electrical isolation between two circuits is needed.
