Primary Supply Voltage, 3.0 V to 5.5 V.
Ground 1. Ground reference for the isolator primary side. Pin 2 and Pin 8 are internally connected to each other, and
it is recommended that both pins be connected to a common ground.
Logic Output A.
Logic Output B.
Regulation Control Input. This pin must be connected to the RC OUT pin of a master iso Power device or tied low. Note
that this pin must not be tied high if RC SEL is low; this combination causes excessive voltage on the secondary side,
damaging the ADuM5202 and possibly the devices that it powers.
Control Input. Determines self-regulation mode (RC SEL high) or slave mode (RC SEL low), allowing external regulation.
This pin is weakly pulled to the high state. In noisy environments, tie this pin either high or low.
Data Enable Input. When this pin is high or not connected, the primary output is active; when this pin is low, the
output is in a high-Z state.
Ground Reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected to each other, and it is recommended
that both pins be connected to a common ground.
No Internal Connection.
Output Voltage Selection. When V SEL = V ISO , the V ISO setpoint is 5.0 V. When V SEL = GND ISO , the V ISO setpoint is 3.3 V.
In slave regulation mode, this pin has no function.
Logic Input B.
Logic Input A.
Secondary Supply Voltage. Output for secondary side isolated data channels and external loads.

Self regulation mode, normal operation.
This supply configuration is not recommended due to extremely poor efficiency.
Part runs at maximum open-loop voltage; therefore, damage can occur.
Power supply is disabled.
Slave mode, RC OUT(EXT) supplied by a master iso Power device.

H refers to a high logic, L refers to a low logic, and X is don’t care or unknown.
V DD1 must be common between all iso Power devices being regulated by a master iso Power part.
