Figure 25 Open Load Detection in OFF Electrical Equivalent Circuit
7.3.3.3 Open Load Diagnostic Timing
Figure 26 shows the timing during either Open load in ON or OFF condition when the DEN pin is HIGH. Please
note that a delay t_{sIS(FAULT_OL_OFF)} has to be respected after 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.
