device can also deassert the PG output or turn off the
external MOSFET when the voltage is outside the critical
limits (see Figure 3). Table 28 shows the behavior for the
three possible states of the PROT input. Note that the
PROT input does not affect the device response to the
UV or OV warning digital comparators; it only determines
the system response to the critical digital comparators
(see Tables 3a, 3b, and 28).
In a typical application, the UV1 and OV1 thresholds
would be set closer to the nominal output voltage, and
the UV2 and OV2 thresholds would be set further from
nominal. This provides a progressive response to a
voltage excursion. However, the thresholds can be con-
figured in any arrangement or combination as desired to
suit a given application.
