______________________________________________________________________________________
Use the following formulas to determine the high/low
threshold levels and the hysteresis:
VL-H = VPFI x (1 + R5 / R6 +R5 / R7)
VH-L = VPFI x (1 + R5 / R6 ) + (VPFI - VTERM) [R5 / (R7 +
R8)]
VHYS = VPFI x (R5 / R7 ) - (VPFI - VTERM) [R5 / (R7 +
R8)]
where VL-H is the threshold level for the monitored volt-
age rising and VH-L is the threshold level for the moni-
tored voltage falling.

COMMENT
Initial state
Low
Don’t care
Off
ENABLE/ENABLE1 is pulled to GND through internal pulldown.
OUT/OUT1 is disabled.
Turn-on state
High
Don’t care
On
ENABLE/ENABLE1 is externally driven high turning OUT/OUT1
on. HOLD is pulled up to OUT/OUT1.
Hold setup state
High
Low
On
HOLD is externally pulled low while ENABLE/ENABLE1
remains high, and the regulator latches on.
Hold state
Low
On
ENABLE/ENABLE1 is driven low (or allowed to float low by an
internal pulldown). HOLD remains externally pulled low
keeping OUT/OUT1 on.
Off state
Low
High (floats
high)
Off
HOLD is driven high (or allowed to float high by the internal pullup)
while ENABLE/ENABLE1 is low. OUT/OUT1 is turned off and
ENABLE/ENABLE1 and HOLD logic returns to the initial state.
