GENERAL DESCRIPTION

The ADuM4121-1-EP1 is a 2.3 A isolated, single-channel driver

that employ Analog Devices, Inc., iCoupler® technology to provide

precision isolation. The ADuM4121-1-EP provides 5 kV rms

isolation in the wide-body, 8-lead SOIC package. Combining high

speed CMOS and monolithic transformer technology, this

isolation component provides outstanding performance

characteristics superior to alternatives such as the combination

of pulse transformers and gate drivers.

The ADuM4121-1-EP operates with an input supply ranging

from 2.5 V to 6.5 V, providing compatibility with lower voltage

systems. In comparison to gate drivers that employ high voltage

level translation methodologies, the ADuM4121-1-EP offers the

benefit of true, galvanic isolation between the input and the output.

The ADuM4121-1-EP includes an internal Miller clamp that

activates at 2 V on the falling edge of the gate drive output,

supplying the driven gate with a lower impedance path to reduce

the chance of Miller capacitance induced turn on.

The ADuM4121-1-EP provides reliable control over the switching

characteristics of insulated gate bipolar transistor (IGBT)/metal

oxide semiconductor field effect transistor (MOSFET) configurations

over a wide range of switching voltages.

Additional application and technical information can be found

in the ADuM4121-1 data sheet.
