GENERAL DESCRIPTION
The EVAL-ADuM3221EBZ supports the ADuM3220/
ADuM3221 isolated gate drivers. It is compatible with IGBT/
MOSFETs in TO-263 or TO-252 packages. The evaluation board is
ideal for evaluating the ADuM322x family with different power
devices. It comes with an ADuM3221A installed.

PAD LAYOUT FOR THE DUT
Figure 4 and Figure 5 show the top and bottom layer artwork of
the EVAL-ADuM3221EBZ evaluation board, respectively. Q1
and Q2 can be populated with TO-263 or TO-252 MOSFETs or
IGBTs with the footprint shown in Figure 2. C4 and C5 are 2.2 nF
and represent a typical gate capacitance. If MOSFETs/IGBTs are
soldered to Q1 and Q2, remove these capacitors. R5 and R6 add
resistance in series with the gates to control the edges of the gate
driver. If the outputs have a lighter load than 2 nF, the resistance
of R5 and R6 may need to increased.

INPUT POWER CONNECTIONS
Connect the input side supply, VDD1 (3 V to 5.5 V) to J2 and
its return to J3 (GND1).
OUTPUT POWER CONNECTIONS
Connect the output supply voltage, VDD2 (4.5 V to 18 V) of the
ADuM3220/ADuM3221 to J4 and its return to J5 (GND2).
I/O CONNECTIONS
Connect Logic Input A/VIA and Logic Input B/VIB to an
external logic signal via J1 or TP1/TP2. The two logic inputs
have 50 Ω terminations. The collector/drain outputs of the two
IGBTs/MOSFETs, Q1 and Q2, have labeled wire pads.
