The SI8230AD-D-IS3 is an isolators-gate driver. It is designed to safely transfer signals across an isolation barrier between two electrically varied circuits while ensuring safety. It guarantees isolation of at least 2500V RMS between the input and output side and is highly efficient and effective in its operation.

Application Field
The SI8230AD-D-IS3 can be used in any application requiring isolated power or signal transfers. This includes safety isolation in medical and industrial applications, as well as isolating bio-signals from noise in automotive systems. It is also commonly used in industrial process automation, providing isolation for data transfer links in distributed control systems (DCS), and signal control in PLCs.

Working Principle
The SI8230AD-D-IS3 consists of two isolated driver circuits. It operates using a magnetically coupled transformer, where an electrical signal is transmitted across an isolation barrier by magnetic fields produced by the transformer windings. The signal passes from the input side of the driver to theOutput side without any physical connection between the two circuits. This also eliminates noise or other interference and ensures safe transfer of digital signals.

The SI8230AD-D-IS3 is also designed to reduce EMI and RFI emission due to its low-power clock consumption. Power is supplied to the driver via an AC isolate power supply. This power supply is necessary to separate the input and the output sides of the driver to guarantee isolation. This also prevents any current leakage from one side of the driver to the other.

The device is also capable of switching both AC and DC signals and uses a TTL compatible logic level input with 5, 12, 15, and 24VDC operating voltage. Its transformer incorporated in the driver is designed to isolate input and output sides of the driver and also provide fast switching speeds. This allows for high speed communication between isolated circuits, ensuring safe and reliable performance of the device.

The SI8230AD-D-IS3 is a cost-effective solution for many isolation applications. It is designed with a compact and robust structure, making it suitable for use in harsh environments. Furthermore, its integrated protection from malfunctions, short-circuits, and over-current, ensures maximum safety and reliability.
