Introduction

Digital Isolators are used to allow electrical isolation between electronic devices, particularly in scenarios where two completely separate power supplies are needed. Isolators can also be used to protect against electric shock, or to protect connected equipment from any damage or degradation caused by electrical noise. This article will discuss the application field and working principle of SI8716BC-A-IP, a series of high performance isolation-capable digital signal controllers.

Application Field

The SI8716BC-A-IP series is a series of integrated and isolated 8-bit microcontrollers. It is designed for a wide range of applications and performs best when used in HVAC and small motor control applications. It also provides reliable digital isolation in power supplies, automotive systems, and medical equipment. The SI8716BC-A-IP additionally offers a variety of onboard features including high speed operation and programmability which allow for precise electrical isolation and control. It also features a SPI (Serial Peripheral Interface) for communication and a watchdog timer.

Working Principle

The SI8716BC-A-IP works by dividing the circuit into two completely isolated sections; the primary and the secondary. It achieves electrical isolation using an integrated digital signal converter to send and receive signals between the two sections without a direct electrical connection. This prevents any noise or pollution between the two signals from interfering with or damaging the equipment. The cross-regulation between the two sections is also managed by the digital isolator, ensuring that any ground loops or other potential hazards are avoided.

The SI8716BC-A-IP series digital isolator has several other features which make it an ideal choice for isolation applications. Firstly, it is able to detect any power failure in the primary section and switch over to the secondary section for continued operation. It also offers adjustable dead time to further improve the isolation performance. The digital isolator is also highly resilient, with an EMI-shielding of up to 35dB.

The SI8716BC-A-IP digital isolator also features a built-in watchdog timer, which can be triggered to reset the system if no signals are received or if the system encounters any other issues. This provides improved system robustness, ensuring that the system functions properly even in the event of any potential issues. Finally, the digital isolator has a comprehensive environmental protection system, such as temperature protection which ensures that the circuit does not become critically overheated.

Conclusion

In conclusion, SI8716BC-A-IP series digital isolator is an ideal choice for isolation applications, due to its combination of reliable isolation capabilities and impressive onboard features. It provides robust electrical isolation between its two sections, while its adjustable dead time and watchdog timer help improve system robustness and overall system performance. Its temperature protection ensures safe and reliable operation, making it a secure choice for digital disconnection applications.
