SI8284CC-IS

The SI8284CC-IS is an Isolator - Gate Driver from Silicon Laboratories. It is a unique product that enables complete isolation of signals and equipment while also delivering very accurate data. This device is especially useful in applications where noise, current, heat, or magnetic fields are potential concerns. In this article, we will discuss the application field and working principle of the SI8284CC-IS.

Application Field

The SI8284CC-IS isolator is designed to be used in applications where electrical isolation of signals and equipment is required. It is commonly used in industrial and automotive systems to help protect from electrical noise and to improve signal integrity. Since it is an isolator, it can reduce the effect of electromagnetic interference (EMI) on critical systems, which can adversely affect the performance and reliability of the system. In addition, it can also be used in medical equipment, military systems, and instrumentation.

The SI8284CC-IS provides up to 4 kVrms (kilo-volts root-mean-square) of isolation, which is suitable for many applications. This isolator also has very low propagation delay (<50 ns) and rise/fall times (<100 ns) which makes it particularly suitable for high-speed signals that require very fast timing control.

Technical Specification

The device is a high-performance, low-power isolator with an input voltage range of 1.7 V to 5.5 V. It features 4 kVrms of electrical isolation, a high data transfer rate up to 16 Mbps, and an isolation capacitance of less than 5 pF. The device also has very low propagation delay (as low as 50 ns) and rise/fall times (as low as 100 ns) making it ideal for high-speed applications. It also has an integrated 5 mA SMPS drive, which allows for controlled output current.

Working Principle

The working principle of the SI8284CC-IS is based on an integrated optocoupler. The optocoupler is a device that transfers electrical signals across an isolating material such as air, plastic, or glass. When an electrical signal is applied to the input of the optics coupler, the light source inside captures some of the energy and converts it into light, which is then transmitted across the gap. The light is then detected by a photodiode on the other side of the gap, which generates an electrical signal, thus providing electrical isolation between the input and the output.

The SI8284CC-IS features an integrated switching regulator, which provides the necessary power to drive the optical components. This device also features an additional channel, which can be used for monitoring the device\'s temperature and voltage. The combination of all these features makes the SI8284CC-IS a powerful, flexible, and reliable isolator.

Conclusion

The SI8284CC-IS isolator from Silicon Laboratories is a unique device that provides electrical isolation for signals and equipment while also providing very accurate data transfer. This device is especially useful in applications where noise, current, heat, or magnetic fields are potential concerns. The device has a wide range of features including an integrated optocoupler, a 5 mA SMPS drive, and an integrated voltage and temperature monitoring channel. It provides up to 4 kVrms of electrical isolation, a high data transfer rate up to 16 Mbps, and an isolation capacitance of less than 5 pF, making it suitable for various applications.
