Comparator hysteresis can be increased with the addition of
resistor R
H
. The hysteresis equations have been simplified and
do not account for the change of input current I
in
as V
in
crosses
the comparator threshold. The internal resistance, R
in
is simply
calculated using I
in
= 0.26 A at 2.6 V.
