DESCRIPTION

The LTC®4331 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.
