Pin No. Mnemonic Description

1

VDD1

Primary Supply Voltage, 4.5 V to 5.5 V. Pin 1 and Pin 7 must be connected to the same external voltage source.

2, 8 GND1

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.

VOC

Logic Output C.

6

VOD

Logic Output D.

7

RCOUT

Regulation Control Output. This pin is connected to the RCIN of a slave isoPower device to allow the ADuM5401W

to control the regulation of the slave device.

9, 15 GNDISO

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.

10

VSEL

This pin must be connected to VISO for proper operation of the part.
