♪ Isolation ♪

00:00:03.760 --> 00:00:06.320
One of the questions we get at NVE is,

00:00:06.320 --> 00:00:10.280
"What's an isolator, and why are they needed?"

00:00:10.280 --> 00:00:13.421
Isolators transmit data or power 
without an electrical connection.

00:00:13.421 --> 00:00:15.838
A key benefit is electrical safety.

00:00:18.560 --> 00:00:24.000
The creepy doll represents a person, 
and the resistor represents human tissue.

00:00:24.000 --> 00:00:25.840
The resistor is grounded,

00:00:25.840 --> 00:00:27.461
which happens if we're standing on the ground.

00:00:27.867 --> 00:00:29.225
Then if we touch something, 

00:00:29.225 --> 00:00:31.480
like an appliance that's 
at a different potential 

00:00:31.480 --> 00:00:33.027
and not isolated,

00:00:33.263 --> 00:00:35.411
a dangerous current could go through us.

00:00:36.440 --> 00:00:41.192
The tester is set for 2500 volts, 
which is a common safety standard.

00:00:41.834 --> 00:00:45.560
2500 volts is a higher voltage 
than you'd normally encounter,

00:00:45.560 --> 00:00:48.005
so there's a safety buffer for surges.

00:00:49.221 --> 00:00:52.355
One of our isolators is between
the tester and the doll,

00:00:52.355 --> 00:00:53.659
so the doll is safe.

00:00:55.280 --> 00:00:57.720
This is the smallest isolator 
in the world 

00:00:57.720 --> 00:01:00.015
that meets the 2500-volt standard.

00:01:00.150 --> 00:01:04.042
It's just three millimeters square--
less than an eighth of an inch.

00:01:06.440 --> 00:01:08.973
The UL standard is for a one minute test.

00:01:12.520 --> 00:01:15.027
And the isolator passes.

00:01:17.797 --> 00:01:21.047
But can just any integrated circuit
provide isolation?

00:01:22.283 --> 00:01:24.488
Here's a garden-variety IC--

00:01:24.488 --> 00:01:26.772
This is voltage regulator we had in the lab.

00:01:29.744 --> 00:01:33.474
It fails to hold off the voltage,
so the resistor smokes and breaks.

00:01:34.960 --> 00:01:39.800
2500 volts and 30 milliamps 
is not just dangerous to creepy dolls...

00:01:39.800 --> 00:01:42.680
...it can hurt you.

00:01:42.680 --> 00:01:44.016
So be sure your electrical appliances are isolated.

00:01:44.860 --> 00:01:47.240
NVE's unique spintronic isolators

00:01:47.240 --> 00:01:49.223
have the highest isolation voltages,

00:01:49.661 --> 00:01:50.960
the longest life, 

00:01:50.960 --> 00:01:53.726
and the smallest packages
in the industry.
