Si840x I²C, SMBus, Power Supply Communication Isolator Evaluation Kit


The Si840xI2C-KIT I²C digital isolator evaluation kit provides a convenient engineering break out board for easy evaluation of the Si840x series of I²C isolators. This kit comes populated with all versions of Silicon Labs' 2.5 kV I²C isolator products which are based on Silicon Labs' industry-leading CMOS isolation technology. Compared to optocoupler-based solutions, Silicon Labs' CMOS isolation technology delivers substantial gains in performance, reliability, cost and power consumption.

The Si840xI2C-KIT evaluation kit offers an overview of the Si84xx isolation product family with three different bidirectional I²C compliant isolators and a two-channel isolator.
