GENERAL DESCRIPTION
The ADuM5401/ADuM5402/ADuM5403/ADuM5404
1
devices
are quad-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
500 mW of regulated, isolated power at either 5.0 V from a 5.0 V
input supply or 3.3 V from a 3.3 V supply. This eliminates 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 the magnetic components of the
dc-to-dc converter. The result is a small form factor, total isolation
solution.
The ADuM5401/ADuM5402/ADuM5403/ADuM5404 isolators
provide four independent isolation channels in a variety of
channel configurations and data rates (see the Ordering Guide
for more information).

The contributions of supply current values for all four channels are combined at identical data rates.
The V
ISO
supply current is available for external use when all data rates are below 2 Mbps. At data rates above 2 Mbps, the data I/O channels draw additional current
proportional to the data rate. Additional supply current associated with an individual channel operating at a given data rate can be calculated as described in the
Power Consumption section. The dynamic I/O channel load must be treated as an external load and included in the V
ISO
power budget.
3
The power demands of the quiescent operation of the data channels cannot be separated from the power supply section. Efficiency includes the quiescent power
consumed by the I/O channels as part of the internal power consumption.
4
This current is available for driving external loads at the V
ISO
pin. All channels are simultaneously driven at a maximum data rate of 25 Mbps with full capacitive load
representing the maximum dynamic load conditions. Refer to the Power Consumption section for calculation of available current at less than the maximum data rate.
