How Does The I2C Isolator 6 Click Board™ Work?
The I2C Isolator 6 Click Board™ is based on the ADUM2250, a two-channel, 5kVRMS I2C digital isolator from Analog Devices, suitable for hot-swap applications. The ADUM2250 bidirectionally buffers the two I2C signals across the isolation barrier while providing 5kVRMS of galvanic isolation. It transfers digital signals with data rates up to 1MHz between circuits with different power domains at ambient temperatures. It offers the glitch-free operation, excellent reliability, and very long operational life. The wide temperature range and high isolation voltage make the device ideal for harsh industrial environments.
The I2C Isolator 6 Click Board™ also possesses two terminals labelled as VIN and SDA/SCL at the top of the Click board™, where VIN represents the isolated-side power supply of the isolator, while the other corresponds to the isolated bidirectional logic-bus terminal.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
