Description

The Si86S60x series of isolators are single-package galvanic

isolation solutions for I2C and SMBus serial port applications.

These products are based on Skyworks proprietary

capacitive isolation technology and offer shorter propagation

delays, lower power consumption, smaller installed

size, and more stable operation with temperature and age

versus optocouplers or other digital isolators. All devices in

this family include bidirectional SDA and/or SCL isolation

channels with open-drain, 35 mA sink capability that operate

to a maximum frequency of 1.7 MHz. The 8-pin versions

supports bidirectional SDA and SCL isolation; the Si86S602

supports bidirectional SDA and unidirectional SCL isolation,

and the 16-pin versions (Si86S605, Si86S606) feature two

unidirectional isolation channels to support additional system

signals, such as interrupts or resets. All versions contain

protection circuits to guard against data errors when an

unpowered device is inserted into a powered system. Small

size, low installed cost, low power consumption, and short

propagation delays make this family the optimum solution

for isolating I2C and SMBus serial ports. Automotive grade

products are available. These products are built using 

automotive-specific flows at all steps in the manufacturing

process to ensure the robustness and low defectivity

required for automotive applications.
