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 iCoupler 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.
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.
