In the News
NVE was prominently covered in a recent EDN cover story, “Draw the line: Isolation shields systems from shocking surprises.”

You must design isolation into your circuits if you want to ensure user safety, eliminate ground loops, and reduce noise.

Halloween Application Corner
PumpkinIsolating Scary Voltages

By Sandy “the Count” Templeton
Director, Isolator Product Development and Applications

Witches, werewolves, vampires, and line voltage top the list of things electronic designers don’t want to deal with.

Fortunately we have the silver bullet for line-voltage interfaces: isolators.

But not just any isolators. Optocouplers can wear out and may be damaged by ac inputs. Digital-input isolators are tricky to interface to high voltage.

IL600-Series passive input isolators provide immortality and require only simple resistive current limiting to interface to virtually any input voltage.

In this illustrative circuit, “Monitor Out” goes low when line voltage exceeds approximately 100 V, and high when line voltage drops below approximately 10 V:

Isolated 120 VAC Line Monitor
Isolated 120 VAC Line Monitor

An open-drain output version is shown for added flexibility handling output voltage goblins.

So happy Halloween, and don't let line voltage ghosts scare you.
