ADuM5230
INSULATION LIFETIME
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of
insulation degradation depends on the characteristics of the
voltage waveform applied across the insulation. In addition to
the testing performed by the regulatory agencies, Analog
Devices conducts an extensive set of evaluations to determine
the lifetime of the insulation structure within the ADuM5230.
Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage.
Acceleration factors for several operating conditions are
determined. These factors allow calculation of the time to
failure at the actual working voltage. Table 7 summarizes the
peak voltages for 50 years of service life for a bipolar ac
operating condition and the maximum Analog Devices
recommended working voltages. In many cases, the approved
working voltage is higher than the 50-year service life voltage.
Operation at these high working voltages can lead to shortened
insulation life in some cases.
The insulation lifetime of the ADuM5230 depends on the
voltage waveform type imposed across the isolation barrier.
The i Coupler insulation structure degrades at different rates
depending on whether the waveform is bipolar ac, unipolar ac,
or dc. Figure 26, Figure 27, and Figure 28 illustrate these
different isolation voltage waveforms.
Bipolar ac voltage is the most stringent environment. The goal
of a 50-year operating lifetime under the ac bipolar condition
determines the maximum working voltage recommended by
Analog Devices.
Data Sheet
In the case of unipolar ac or dc voltage, the stress on the insu-
lation is significantly lower. This allows operation at higher
working voltages while still achieving a 50-year service life. The
working voltages listed in Table 7 can be applied while maintaining
the 50-year minimum lifetime, provided the voltage conforms to
either the unipolar ac or dc voltage cases. Any cross-insulation
voltage waveform that does not conform to Figure 27 or Figure 28
should be treated as a bipolar ac waveform, and its peak voltage
should be limited to the 50-year lifetime voltage value listed in
Table 7. Note that the voltage presented in Figure 27 is shown as
sinusoidal for illustration purposes only. It is meant to represent
any voltage waveform varying between 0 V and some limiting
value. The limiting value can be positive or negative, but the
voltage cannot cross 0 V.
