Digital isolators are increasingly being used in electronics applications to improve electrical safety and reduce electromagnetic interference (EMI). The SI8642BD-B-IS2 is a digital isolator from Silicon Laboratories, Inc. that meets these requirements while providing high-speed data transfer and low power operation. This article will discuss the application field and working principle of the SI8642BD-B-IS2.

The SI8642BD-B-IS2 is an ideal device to use in accurate signal conditioning applications, such as motor control systems, medical equipment, and automotive applications. The device offers transmissions of up to 2000V/μs of noise-immunity without the risk of ground loops or EMI emission. In addition, the device supports data rates up to 12 Mbps, meaning it can quickly and accurately condition noisy signals.

The device works by isolating two circuits with an opto-electronic barrier. This barrier is created with an infrared LED and a silicon phototransistor. The LED is driven by the input current, which creates an infrared light that triggers the phototransistor. This prepares the opto-coupler to be used, and allows the data to be transmitted across the circuit barrier. The data is encoded in the carrier frequency of the infrared light, which is then picked up by the phototransistor and converted back into current. This current is then used to drive the output side of the isolator, completing the process.

In addition to its high speed operation, the SI8642BD-B-IS2 is also noted for its low power consumption. The device only needs 3.0V/0.3mA for operation, making it one of the most power efficient digital isolators currently available. This low power consumption makes it an ideal choice for battery powered applications, such as industrial and consumer electronics.

Finally, the SI8642BD-B-IS2 is an excellent choice for a wide range of applications due to its high speed data transfer and low power consumption. The device can quickly and accurately condition noisy signals, ensuring electrical safety and reducing EMI from high voltage systems. As a result, the SI8642BD-B-IS2 is an ideal solution to use in a variety of high-speed applications.
