NEW! Low-Power Isolators
IL017 DiagramsWith typical total quiescent current of just 0.3 mA per channel, the new IL01x-Series low-power isolators draw just one-fourth the power of our flagship products.

Even with the low power, the new parts provide remarkable performance:
  • 10 Mbps guaranteed maximum data rate
  • No carriers or clocks for low EMI
  • 44000 year barrier life
  • 2.5 kV isolation
  • -40°C to +100°C
The new devices use NVE’s patented low-power spintronic Tunneling Magnetoresistance (TMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation, best-in-class barrier resistance, and virtually unlimited barrier life.

VDE V 0884-11 and UL 1577 approvals are pending. The four-channel versions use NVE’s unique True 8™ wide-body SOIC-16 package with full 8-millimeter creepage in accordance with IEC60601.

Applications include:
  • 4-20 mA loop-powered controls
  • Battery-powered instruments
  • SPI
Samples of two popular channel configurations are available now, with two more coming soon:

Lab Results
Low-Power Isolator Demonstration 
We went into the lab to demonstrate the best-in-class efficiency of the new IL017 low-power isolator, making it ideal for SPI interfaces powered by 4-20 mA current loops:

Recent Exhibitions
Embedded World 2018 
NVE isolators at were recently on display at Embedded World in Germany.

Featured products included NVE’s unique ultraminiature MSOP isolators and ultra-rugged, best-in-class six-kilovolt isolators.
Upcoming Conferences
NVE researcher Joe Davies co-authored a paper to be presented at the Intermag Conference April 26 in Singapore. The paper is titled, “A Magneto-elastic Correlator Using Acoustic Wave Pumping of Spin Waves.”
Foolproof Current Sensing
AAL024 Over Trace
Unlike shunt resistors, the new AAL024-10E noncontact current sensor has inherently transient immunity, is self-limiting, has inherent rectification, and is lossless for no self-heating.

That means no ancillary components are required, and makes for small, simple, systems.

And with typical current sensitivity of up to 300 mV/A with a 5V supply, you don’t even need an amplifier.

Chicken Salad “Current” Sensor
4/1/18—The new AAL024 noncontact current sensor can not only detect current, it can detect whether objects are current. And since the sensor is noncontact, you just need to get it close to the object under test.

Here’s a reference circuit with an adjustable threshold and complementary “CURRENT” and “NOT CURRENT” outputs:
Current Sensor for Food  
Circuit for detecting “current” and “not current” objects.
In real-world field testing at NVE, the sensor correctly identified a number of items as NOT CURRENT, including a chicken salad sandwich, a fizzless open can of Mountain Dew, and today’s edition of USA Today in the lunch room. In the parking lot, the sensor identified a Ford Crown Victoria. And in the product labs, it easily exposed some shunt resistors and Hall effect sensors as NOT CURRENT.
