Bidirectional I²C isolators

23 January 2013 Analogue, Mixed Signal, LSI

Texas Instruments introduced a bidirectional isolator family compatible with I²C interfaces that consumes as much as 38% less power than competitive devices. Both of the new ICs can replace a typical implementation of 16 or more discrete devices to isolate the I²C signal in industrial applications. In addition, the ISO1540 and ISO1541 offer better transient immunity and faster switching times than optocouplers. This performance provides longer-lasting isolation in a variety of applications, such as power supplies, networking, telecommunications, Power over Ethernet (PoE) and battery management systems. The ISO1540 is targeted at applications that have multiple masters while the ISO1541 is for single-master applications.
