Omnipolar vs. Bipolar Magnetic Sensors
NVE offers both omnipolar and bipolar sensors. This slideshow illustrates the difference:
Omnipolar vs. bipolar sensors Most NVE sensors are omnipolar, meaning they operate with either a north or south magnetic field and release when the field strength drops below a certain threshold. Omnipolar parts are used in a wide range of applications.
Bipolar sensors have opposite polarity magnetic operate and release points. They are ideal for magnetic encoders that have alternating north/south poles, or other applications where one polarity of field is required to turn the parts on and the opposite polarity to turn them off.

ISO 9001:2008 Certification
NVE was recently certified under the new ISO 9001:2008 standard following a rigorous external audit. Customer surveys continued to give NVE very high marks for product quality and on-time shipments.
NVE has been ISO certified since 1997.
ISO 9001:2008 sets requirements to achieve customer satisfaction through consistent products and services.
It also includes a requirement for the continual improvement of the Quality Management System.
The scope of NVE’s Quality Management System includes design, development and manufacture of
semiconductor-based magnetic/ semiconductor products, processes, systems, and services.

Isolator Power Consumption
By Sandy Templeton
Director, Isolator Product Development and Applications
Because of their different architectures, NVE’s three digital isolator families have different dynamic power consumption profiles. IL600 Series isolators are similar to optocouplers. They use a 5 mA coil current, but the dynamic power consumption component is very low. IL500 and IL200/700 Series isolators are edge-sensitive devices, drawing current on transitions but with low quiescent power consumption. The graph below shows an overview
of per-channel power consumption with 3.3 V supplies.
Isolator No-Load Power Consumption Per Channel at 3.3 V
IL500 Series isolators have a maximum data rate of 2 Mbps. IL200/700 Series isolators have unsurpassed speed and have the lowest power consumption up to approximately
30 Mbps. Above 30 Mbps, the IL6xx becomes the lowest average power user.
