NVE's AD021-00E GMR Switch integrates GMR sensor elements with digital onboard
signal processing electronics. The GMR Switch has less field sensing errors than
other magnetic sensors, and magnetic field operate points are stable over voltage
and temperature extremes. This enables high precision, tight-tolerance magnetic
sensing assemblies.

AD924-00E Sensors are for use with external high-current output transistors in
industrial control environments. The parts provide the same precise magnetic performance
as NVE's GMR Digital Switches with the addition of output stage short circuit
protection (SCP). The protection circuit shuts off the output stage if there is
a short circuit, then turns it back on after a specified interval. The sensor,
combined with external reverse battery and overvoltage protection, results in
a "bulletproof" assembly.

The IL614-3E is a 3.3/5V, 3-channel (2 transmit, 1 receive), 100 Mbps isolated signal coupler with CMOS outputs, which can be used to replace opto-couplers in many standard isolation functions. The devices are manufactured with NVE's IsoLoop spintronic GMR technology giving exceptional small size and low power dissipation. The passive input structure allows direct interface to a very wide range of voltage inputs. A single resistor is used to set maximum current for input voltages above 0.5 V. 20 kV/microsecond transient immunity. 16-pin 0.15" SOIC package.

product information
IL6xxCMTI-Series isolators are
optimized for driving MOSFETs either directly or with an
external gate driver.
Resistors set the input current, and five milliamps guarantees
switching. The inputs can be configured as non-inverting or
inverting.
CMTI-grade isolators are 100% tested to ensure each part has
at least 200 kV/µs minimum Common-Mode Transient
Immunity. Simple external deglitch circuitry can extend the
CMTI to an extraordinary 350 kV/µs typical.
The parts also have an extended supply range of up to 6.6 volts
for compatibility to directly drive a range of power
MOSFETs or gate driver ICs. The parts provide full 2.5 kV isolation.
The IL610CMTI-1E is a single-channel version in an ultraminiature MSOP8 package.
The ILDC12-15E is a one-quarter watt fully-regulated 3.3V-to-5V DC-DC boost convertor in an ultraminiature 3 mm x 5.5 mm DFN6 package. The "V" suffix indicates an extended creepage package and full 2.5 kV isolation.
The part can be used to generate isolated RS-485 bus supplies or to power high-side gate supplies in H-bridges.
The device minimizes board space and parts count, requiring just three external capacitors. No additional regulation is required and there is no minimum load.
Frequency hopping and shielding reduce EMI, and ferrite beads are not necessary for EMI mitigation.
A high-temperature process allows up to 175 °C junction temperature for full power up to 125 °C operating temperature with no derating. Integrated short-circuit protection avoids excessive power dissipation.
NVE’s proven IsoLoop® isolation technology and a unique ceramic/polymer composite barrier provide virtually unlimited barrier life.
