7.3.3.3 Open Load Diagnostic Timing
Figure 26 shows the timing during either Open load in ON or OFF condition. Please note that a delay t_{sIS(OT_BLANK)}
has to be respected between the falling edge of the input and rising edge of the DEN, when applying an open load
in OFF diagnosis request, otherwise the voltage V_OUT cannot be guaranteed and the diagnosis can be wrong.
