GENERAL DESCRIPTION
The ADuM4221/ADuM4221-1/ADuM4221-2 are 4 A isolated, half bridge gate drivers that employ the Analog Devices, Inc.,
iCoupler® technology to provide independent and isolated
high-side and low-side outputs. The ADuM4221/ADuM4221-1/ ADuM4221-2 provide 5700 V rms isolation in an increased creepage wide body, 16-lead SOIC_IC. 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. 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/ADuM4221-1/
ADuM4221-2 offer the benefit of true, galvanic isolation
between the input and each output.
The ADuM4221/ADuM4221-1 each have built in overlap
protection and allow dead time adjustment. A single resistor
between the dead time pin (DT) and the GND1 pin sets the
dead time on the secondary side between the high-side and the low-side outputs. The ADuM4221-2 does not have overlap
protection nor dead time control.
An internal thermal shutdown (TSD) sets outputs low if
the internal temperature on the ADuM4221/ADuM4221-1/
ADuM4221-2 exceeds the TSD temperature. As a result,
the ADuM4221/ADuM4221-1/ADuM4221-2 provide 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.
