Table 12. Pin Function Descriptions Pin No. Mnemonic Description
1, 7 VDD1 Primary Supply Voltage, 3.0 V to 5.5 V. Pin 1 and Pin 7 are internally connected to each other, and it is recommended that both pins be externally connected to a common power source. 2, 8 GND1 Ground Reference for the Primary Side of the Converter. 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, 11, 12, 14 NC No Internal Connection. 4 RCIN Regulation Control Input. In slave power configuration (RCSEL low), this pin is connected to the RCOUT pin of a master isoPower device, or it is tied low to disable the converter. In master or standalone mode (RCSEL high), this pin has no function. This pin is weakly pulled to the low state. In noisy environments, it should be tied low or tied to a PWM control source. This pin must not be tied high if RCSEL is low; this combination causes excessive voltage on the secondary side of the converter, damaging the ADuM6000 and possibly the devices that it powers. 5 RCOUT Regulation Control Output. In master power configuration (RCSEL high), this pin is connected to the RCIN pin of a slave isoPower device to allow the ADuM6000 to regulate additional devices. 6 RCSEL Control Input. Sets either standalone/master mode (RCSEL high) or slave mode (RCSEL low). This pin is weakly pulled to the high state. In noisy environments, tie this pin either high or low. 9, 15 GNDISO Ground Reference for the Secondary Side of the Converter. 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, 16 VISO Secondary Supply Voltage Output for External Loads. 3.3 V (VSEL low) or 5.0 V (VSEL high). The 5.0 V output functionality is not guaranteed for a 3.3 V primary supply input. Pin 10 and Pin 16 are internally connected to each other, and it is recommended that both pins be externally connected. 13 VSEL Output Voltage Selection. When VSEL = VISO, the VISO setpoint is 5.0 V. When VSEL = GNDISO, the VISO setpoint is 3.3 V. This pin is weakly pulled to the high state. In noisy environments, tie this pin either high or low. In slave mode, this pin has no function.

H X PWM1 H 5.0 V 5.0 V Master mode operation, self regulating. H X PWM1 L 5.0 V 3.3 V Master mode operation, self regulating. H X PWM1 H 3.3 V 5.0 V This configuration is not recommended due to poor efficiency. H X PWM1 L 3.3 V 3.3 V Master mode operation, self regulating. L RCOUT(EXT) RCIN X X2 X Slave mode, RCOUT(EXT) supplied by a master isoPower device. L L L X X 0 V Low power mode, converter disabled. L H H X X X This combination of RCIN and RCSEL is prohibited. Damage occurs on the secondary side of the converter due to excess output voltage at VISO. RCIN must be low, or it must be connected to a PWM signal from a master isoPower part. 1 PWM refers to the regulation control signal. This signal is derived from the secondary side regulator or from the RCIN input, depending on the value of RCSEL. 2 VDD1 must be common between all isoPower devices being regulated by a master isoPower part.
