GENERAL DESCRIPTION
The ADuM6200/ADuM6201/ADuM62021 are dual-channel
digital isolators with isoPower®, an integrated, isolated dc-to-dc
converter. Based on the Analog Devices, Inc., iCoupler® technology,
the dc-to-dc converter provides up to 400 mW of regulated, iso-
lated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or
at 3.3 V from a 3.3 V supply at the power levels shown in Table 1.
These devices eliminate the need for a separate, isolated dc-to-dc
converter in low power, isolated designs. The iCoupler chip scale
transformer technology is used to isolate the logic signals and for
the magnetic components of the dc-to-dc converter. The result
is a small form factor, total isolation solution.
The ADuM6200/ADuM6201/ADuM6202 isolators provide two
independent isolation channels in a variety of channel configura-
tions and data rates (see the Ordering Guide for more information).

isoPower uses high frequency switching elements to transfer power
through its transformer. Special care must be taken during printed
circuit board (PCB) layout to meet emissions standards. See the
AN-0971 Application Note for board layout recommendations.

1 |CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.7 × VDD1 or 0.7 × VISO for a high input or VO < 0.3 × VDD1 or 0.3 × VISO for a low
input. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges.

Mnemonic Description
1 VDD1 Primary Supply Voltage, 3.0 V to 5.5 V.
2, 8
GND1
Ground Reference for the Primary Side of the Isolator. Pin 2 and Pin 8 are internally connected to each other,
and it is recommended that both pins be connected to a common ground.
3 VIA Logic Input A.
4 VIB Logic Input B.
5 RCIN Regulation Control Input. This pin must be connected to the RCOUT pin of a master isoPower device or tied low.
This pin must not be tied high if RCSEL is low; this combination causes excessive voltage on the secondary side
of the isolator, damaging the ADuM6200 and possibly the devices that it powers.
6
RCSEL
Control Input. Determines self-regulation mode (RCSEL high) or slave mode (RCSEL low), allowing external
regulation. This pin is weakly pulled to the high state. In noisy environments, tie this pin either high or low.
7, 12 NC
No Internal Connection.
9, 15
GNDISO
Ground Reference for the Secondary Side of the Isolator. Pin 9 and Pin 15 are internally connected to each
other, and it is recommended that both pins be connected to a common ground.
10 VE2 Data Enable Input. When this pin is high or not connected, the secondary outputs are active; when this pin is
low, the outputs are in a high-Z state.
11 VSEL Output Voltage Selection. When VSEL = VISO, the VISO setpoint is 5.0 V. When VSEL = GNDISO, the VISO setpoint is 3.3 V.
In slave regulation mode, this pin has no function.
13 VOB Logic Output B.
14 VOA Logic Output A.
16 VISO Secondary Supply Voltage. Output for secondary side isolated data channels and external loads.
