Introduction
The LTC4331 is a point-to-point SMBus compatible I²C slave device extender designed for operation in high noise industrial environments. Using a ±60V fault protected differential transceiver, the LTC4331 can extend an I²C/SMBus bus, including SMBALERT and a control signal, over a single twisted pair differential link up to 1200m. With an extended common mode operating range the solution provides tolerance to large ground differences between nodes. For EMI sensitive environments, a slew rate control pin reduces the EMI emitted from the differential link.
In addition, the LTC4331 can act as an I²C to I²C bridge allowing independent bus frequencies between the local and remote networks. The solution is completely transparent to the master requiring no additional code in most cases; however, a control interface is provided for additional configuration and fault monitoring.
A master controller fully supporting SCL clock-stretching is strongly recommended.
