Low-Power
Isolators |
|
|
 With
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

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:

Foolproof
Current Sensing |
|
|
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.
An evaluation board lets you see how foolproof it really is.

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:
Circuit for detecting “current” and “not current” objects.
