I2C Isolator Click

IC/Module: ISO1540 Bidirectional Isolator

ISO1540 IC is an I2C-compatible, bidirectional isolator with low power consumption. It has a silicon dioxide protective barrier that separates the logic input and output buffers. It blocks high voltages, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry, when used with isolated power supplies.

Two Sets of I2C Pins

The ISO1540 chip aboard Isolator click is connected to two sets of I2C pins. The SDA, SCL pins on the mikroBUS connector and SCL2, SDL2 on the upper edge of the board.

TI’s Capacitive Isolation technology

Isolator click is based on TI's Capacitive Isolation technology, and thus is a better alternative to the common opto-coupler in terms of function, performance, size and power consumption.
