Increasing the Under and Over Voltage Hysteresis
If the internal UV hysteresis is insufficient for a particular system application, then it may be increased by using separate resis-
tor dividers for UV and OV and providing a resistor feedback from UV pin to the PWRGD pin.

Ruvhys can be calculated based on higher UV On voltage (say
42V):
Ruvhys = (Vuvon - Vdiode - Vpwrgdlow)/((Vin-Vuvon)/487k -
Vuvon/16.5k)
= (1.22-0.65-0.4)/((42-1.22)/487k - 1.22/16.5k)
= 17.35k
