IL600A Series Isolators
Dynamic Power Consumption
Power consumption is proportional to duty cycle, not data rate. The use of NRZ coding minimizes power dissipation since no
additional power is consumed when the output is in the high state. In differential mode, where the logic high condition may still
require a current to be forced through the coil, power consumption will be higher than a typical NRZ single ended configuration.
Power Supply Decoupling
47 nF low-ESR ceramic capacitors are recommended to decouple the power supplies. The capacitors should be placed as close as
possible to the appropriate V DD pin.
Maintaining Creepage
Creepage distances are often critical in isolated circuits. In addition to meeting JEDEC standards, NVE isolator packages have
unique creepage specifications. Standard pad libraries often extend under the package, compromising creepage and clearance.
Similarly, ground planes, if used, should be spaced to avoid compromising clearance. Package drawings and recommended pad
layouts are included in this datasheet.
Electromagnetic Compatibility and Magnetic Field Immunity
Because IL600-Series Isolators are completely static, they have the lowest emitted noise of any non-optical isolators.
IsoLoop Isolators operate by imposing a magnetic field on a GMR sensor, which translates the change in field into a change in
logic state. A magnetic shield and a Wheatstone Bridge configuration provide good immunity to external magnetic fields.
Immunity to external magnetic fields can be enhanced by proper orientation of the device with respect to the field direction, the
use of differential signaling, and boost capacitors.
1. Orientation of the device with respect to the field direction
An applied field in the “H1” direction is the worst case for
magnetic immunity. In this case the external field is in the same
NC
V DD
direction as the applied internal field. In one direction it will
tend to help switching; in the other it will hinder switching.
This can cause unpredictable operation.
An applied field in direction “H2” has considerably less effect
and results in higher magnetic immunity.

2. Differential Signaling and Boost Capacitors
Regardless of orientation, driving the coil differentially improves magnetic immunity. This is because the logic high state is driven
by an applied field instead of zero field, as is the case with single-ended operation. The higher the coil current, the higher the
internal field, and the higher the immunity to external fields. Optimal magnetic immunity is achieved by adding the boost
capacitor.

Immunity Description
A DC current of 16 A flowing in a conductor
1 cm from the device could cause disturbance.
A DC current of 56 A flowing in a conductor
1 cm from the device could cause disturbance.
A DC current of 200 A flowing in a conductor
1 cm from the device could cause disturbance.
Data Rate and Magnetic Field Immunity
It is easier to disrupt an isolated DC signal with an external magnetic field than it is to disrupt an isolated AC signal. Similarly, a
DC magnetic field will have a greater effect on the device than an AC magnetic field of the same effective magnitude. For
example, signals with pulses longer than 100 μ s are more susceptible to magnetic fields than shorter pulse widths.
