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.

This Evaluation Board is a complete isolated RS-485 / RS-422 node using the IL4622E isolated transceiver with integrated isolated DC-DC convertor.
These 2 x 3.5-inch (50 x 90 mm) boards include screw terminals and test pads. LEDs indicate DC-to-DC convertor input and output power. A 2s2p board with vias optimizes thermal performance.
The IL4622E is a high-speed, fully-isolated, full duplex differential bus transceiver with an integrated
3.3-to-3.3 volt DC-DC convertor to provide a fully-isolated 3.3 volt bus supply using the controller supply. This level of integration dramatically reduces chip count and board area.
The ILDC11-15E is a one-quarter watt fully-regulated 3.3V-to-3.3V DC-DC convertor in an ultraminiature 3 mm x 5.5 mm DFN6 package. The part can be used to generate an isolated 3.3-volt bus supply from a controller supply.
NVE’s proven IsoLoop® isolation technology and a unique ceramic/polymer composite barrier provide full 2.5 kV isolation and virtually unlimited barrier life.
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.
