Si86S60x: Low Power I2C Isolators

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. 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.
