and intelligent to accommodate demands for centralized control,
optimized production and reduced cost. IO-LinkВ® is becoming
an increasinglyВ popular interface toВ smart sensors and actuators,
combining signaling with power-over-cable technology. The interface
electronics must be rugged, power efficient and compact. Two
new parts capably meet these requirements. The LTCВ®2874 is a
highly integrated IO-Link master-side physical layer interface (PHY)
for four ports. The LTВ®3669 is a device-side PHY incorporating
a step-down regulator and LDO. To appreciate the numerous
features of these devices, it helps to review the requirements
of IO-Link. This article begins with a brief overview of IO-Link
technology, and follows with LTC2874
and LT3669 functions and features.
IO-LINK: POWER AND COMMUNICATION FOR
SMART DEVICES Combining a power feed and a data link inside a cable
assembly isnвЂ™t new,1 but its presence in the world of industrial automation is. IO-Link2 emerged in 2009 as a communication interface between automation control systems …
