ISL83385EIA is a High Voltage, Single Channel, Bus-driven, Inter-Integrated Circuit (I2C) Isolator. It contains a digital isolator and synchronous logic that works together to transfer I2C data between the low-voltage and high-voltage sides of an isolated power supply. The isolator ensures that any changes to the high voltage side of the power supply do not affect the functionality of the low-voltage side. The ISL83385EIA also includes a programmable delay circuit and current limitation.The ISL83385EIA supports up to 32 multiple slaves and hosts, is compliant with I2C specifications, and has a propagation delay of only 4.55 us. The device offers power savings and increased system reliability due to its low power consumption and ESD protection. The ISL83385EIA has excellent output and input transient characteristics, is designed with slew-rate control to reduce inrush current, and is immune to EMI.The ISL83385EIA is an ideal choice for a variety of different applications, such as industrial automation, building automation, medical device control modules, DC/DC converters, power supplies and lighting control systems. It is also well suited for high-voltage applications where noise immunity is required, such as isolated power supplies and motor control applications.The ISL83385EIA\'s working principle is based on the concept of galvanic isolation. It contains a CMOS-based isolator which creates an isolated electrical path between primary and secondary circuits. The device also contains a synchronous logic circuit which works together with the isolator to provide high data rate I2C transfer. The ISL83385EIA\'s digital isolator functions through the transmission of digital signals which are converted into electrical signals by the device\'s transceiver.The ISL83385EIA\'s digital isolator ensures that any electrical or environmental disturbances on the high-voltage side of the power supply will not affect the operation of the low-voltage side. The isolator also functions as an impedance-balancing circuit, which ensures that the data is transmitted without errors. The device also features a programmable delay circuit which allows the system designer to decide the amount of time the signal will take to propagate through the isolator.The ISL83385EIA\'s current limitation helps protect the I2C bus from excessive loads, while the slew-rate control helps reduce inrush current. The EMI immunity of the device offers increased system reliability. Additionally, the device is designed to withstand high temperatures and high voltage transients.In summary, the ISL83385EIA is an ideal device for applications that require high voltage isolation and noise immunity. Its synchronous logic circuit and digital isolator together ensure reliable communication. The device offers power savings, increased system reliability, and immunity to EMI.
