Figure 18 QPI-8 UV and OV fault timing diagram.
Current De-Rating: mounted to QPI-8-EVAL1 evaluation board.
Figure 19 - Current de-rating and power dissipation over ambient temperature range.
The de-rating curve in Figure 19 is based on the maximum
allowable internal component temperature and the 5.5A
maximum rating of the QPI-8. The power dissipation curve is
based on the current squared multiplied by the internal
resistance between the inputs and outputs of the filter. The
internal resistance value is temperature compensated for the
power dissipation curve. The left axis (current) is in amps for
the solid trace, the right axis (power) is in watts for the
dashed trace.
