Figure 20.
Undervoltage detected for <tSRD
1.
VCC goes above VTH+ within tSRD thus power is not disabled after tSRD expires.
2.
tSRD period is set by external capacitor CSRD.
Figure 21.
Undervoltage detected for >tSRD
1.
After tSRD expires VCC is still insufficient (below VTH+) thus power is disabled (EN goes low or EN goes high).
2.
tSRD period is set by external capacitor CSRD.
