GENERAL DESCRIPTION
The ADuM1310
isolator based on Analog Devices, Inc. iCoupler® technology.
Combining high speed CMOS and monolithic coreless trans-
former technology, this isolation component provides outstanding
performance characteristics superior to alternatives such as
optocoupler devices.
By avoiding the use of LEDs and photodiodes, iCoupler
devices remove the design difficulties commonly associated
with optocouplers. The typical concerns that arise with opto-
couplers, such as uncertain current transfer ratios, nonlinear
transfer functions, and temperature and lifetime effects, are
eliminated with the simple iCoupler digital interfaces and stable
performance characteristics. The need for external drivers and
other discretes is eliminated with these iCoupler products.
Furthermore, iCoupler devices run at one-tenth to one-sixth
the power consumption of optocouplers at comparable signal
data rates.
The ADuM1310 isolator provides three independent isolation
channels at data rates up to 10 Mbps. It operates with the supply
voltage of either side ranging from 2.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier.
This product also has a default output control pin. This allows
the user to define the logic state the outputs are to adopt in the
absence of the input V
alternatives, the ADuM1310 has a patented refresh feature that
ensures dc correctness in the absence of input logic transitions
and during power-up/power-down conditions.

... V watchdog timer circuit The magnetic field immunity of the ADuM1310 is determined by CTRL GND the changing magnetic field which induces a voltage in the trans- 2 former’s receiving coil large enough to either falsely set or reset the decoder.

... Given the geometry of the receiving coil in the ADuM1310 and an imposed requirement that the induced voltage be at most 50% of the 0.5 V margin at the decoder, a maximum allowable magnetic field at a given frequency can be calculated.

ADuM1310 POWER-UP/POWER-DOWN CONSIDERATIONS Given that the ADuM1310 has separate supplies on either side of the isolation barrier, the power-up and power-down characteristics relative to each supply voltage need to be considered individually.
