How does the low Ron help on a communication transceiver?

  • Usually the transceivers need to be able to drive 100-200mA, and lower Ron in the Output stage of the transceiver simply means lower voltage-drop which then reduces power dissipation inside the transceiver.
    IO-Link devices are usually mounted right at the edge, where welding is happening, metal gets cut, there’s very little space, and often it’s very hot. Therefore sensors typically are mounted in very small housings, which means producing heat even in the range of 100mW can be a concern.
