GENERAL DESCRIPTION

The ADuM4221 is a 4 A isolated, half bridge gate driver that

employs the Analog Devices, Inc., iCoupler® technology to

provide independent and isolated high-side and low-side outputs.

The ADuM4221 provides 5700 V rms isolation in the increased

creepage wide body, 16-lead SOIC_IC package. Combining

high speed CMOS and monolithic transformer technology,

these isolation components provide outstanding performance

characteristics superior to the alternatives, such as the

combination of pulse transformers and gate drivers.

_IORM= 849 V peak

Increased creepage wide body, 16-lead SOIC_IC

APPLICATIONS

Switching power supplies

Isolated IGBT/MOSFET gate drives

Industrial inverters

Gallium nitride (GaN)/silicon carbide (SiC) compatible

The isolators operate with a logic input voltage ranging from

2.5 V to 6.5 V, providing compatibility with lower voltage systems.

In comparison to gate drivers employing high voltage level

translation methodologies, the ADuM4221 offers the benefit of

true, galvanic isolation between the input and each output.

The ADuM4221 has a built in overlap protection and allows for

dead time adjustment. A single resistor between the dead time

pin (DT) and the GND₁pin sets the dead time on the secondary

side between the high-side and the low-side outputs.

An internal thermal shutdown (TSD) sets outputs low if the

internal temperature on the ADuM4221 exceeds the TSD

temperature. As a result, the ADuM4221 provides reliable

control over the switching characteristics of the insulated gate

bipolar transistor (IGBT)/metal-oxide semiconductor field

effect transistor (MOSFET) configurations over a wide range of

positive or negative switching voltages.
