Digital isolators are essential tools to allow electrical isolation between two circuits, providing simple and cost effective isolation for designs ranging from industrial controls to the smallest of systems. The SI88240BC-ISR, a data isolation and interface isolator, is no exception. This device is optimized for I2C communication which makes it the perfect choice for industrial, medical and other applications that require high speed isolation.

Just as any other isolator, the SI88240BC-ISR device provides isolation between the input and output of a system while still allowing communication without galvanic connection. It operates by using an isolation transformer to provide effective isolation between the two systems and is typically used in applications where interfering signals must be kept isolated and unaffected by external clutters. It also provides a very low jitter performance with I2C, making it an ideal choice for situations where noise and disruption must be eliminated.

The SI88240BC-ISR device has an innovative isolator design which leverages the “Isolation interface” technology. This enables the device to provide high speed communication at data rates up to 1Mbit/s while simultaneously providing more than 5KV rms electrical isolation. It has two independent ports on each side, each can support I2C communication of up to 400 Kbps. The device’s wide bus voltage range (3.0V to 5.5V) is compatible with various embedded systems, allowing for simpler and reliable operation. The optimal performance of the SI88240BC-ISR isolator allows it to operate in various scenarios such as, switching applications, sensors, analog-to-digital or digital-to-analog interfaces, motor and audio applications, and in medical equipment.

Aside from the isolation capability of the device, the SI88240BC-ISR isolator also supports programmability to provide more flexibility. This means that as the application needs of a design changes, the device can be easily reconfigured to match the new requirements. The programmability also enables the isolator device to be customized, making it ideal for quick prototyping.

The working principle of the SI88240BC-ISR isolator is also quite straightforward, it is a full-duplex isolator. It has two 1:2 differential input ports that take data from either side of the system isolator, and two 1:2 differential output ports that send the data back. The data is sent and received by the device through a small electrical transformer which provides electrical isolation between the two systems. This enables the system to communicate without the need for any physical connections. The differential inputs and outputs on both sides of the device are connected through the isolator transformer, thus allowing for bidirectional communication.

In summary, the SI88240BC-ISR device is an excellent choice for isolation applications due to its efficient design, high speed, programmability, robust design and overall low jitter performance. It is a great way to ensure that you’re able to communicate between isolated systems without any interference.
