Power Fail Output (Active Low) - PFOB
The PFOB pin is an open drain, active low output. When the input voltage at PFI
is <0.5V, PFOB will be asserted.

Glitch Immunity at Voltage Inputs
The V1, V2, V3 and V4 inputs have a built-in glitch immunity feature that
prevents nuisance resets during normal operation. Noise and normal voltage
transients can cause these unwanted resets without some type of glitch
immunity. Figure 2 shows the combination of voltage overdrive and duration that
will not cause a reset for V1 and V2 inputs. Figure 3 shows the same data as
applied to the V3 and V4 inputs. Adding a small bypass capacitor to voltage
inputs can improve glitch rejection for very harsh environments.
