Primary Supply Voltage 3.0V to 5.5 V.
Ground 1. Ground reference for isolator primary. Pin 2 and Pin 8 are internally connected, and it is recommended that both
pins be connected to a common ground.
Logic Input A.
Logic Output B.
Regulation Control Input, In slave power configuration (RC
isoPower device, or tied low to disable the converter. In Master/Stand alone mode(RC
function. This pin is weakly pulled to low. In Noisy environments it should be tied to low or to a PWM control source.
Warning -This pin must not be tied high if RC
secondary, damaging the ADuM5000 and possibly devices that it powers.
Control input, Determines self regulation (CTL High) mode or Slave mode(CTL Low)allowing external regulation. This
pin is weakly pulled to high. In noisy environments it should be tied either high or low.
Data Enable Input, When High or NC the Primary output is active, when Low the outputs are in a high Z state..
Ground reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected, and it is recommended that both pins be
connected to a common ground.
Data Enable Input, When High or NC the Secondary output is active, when Low the outputs are in a high Z state..
Output Voltage Selection: When V
is 3.3V. In Slave regulation mode, this pin has no function.
No Internal Connection.
Logic Input B.
Logic Output A.
Secondary Supply Voltage Output for Secondary Isolaton electronics and External Loads, 3.3V (VSEL Low) or 5.0V (V
High), 5.0V output Functioanlity not guaranteed for a 3.3V primary supply input.
