Comparator hysteresis can be increased with the addition of resistor R
H
. The hysteresis equation has been simplified and does not account for the change of input current
I
in
as V
in
crosses the comparator threshold (Figure 8). An increase of the lower threshold V
th(lower)
will be observed due to I
in
which is typically 10 A at 4.3 V. The
equations are accurate to
±
10% with R
H
less than 1.0 k and R

between 4.3 k and 43 k .

Overheating of the logic level power MOSFET due to insufficient
gate voltage can be prevented with the above circuit. When the
input signal is below the 4.3 V threshold of the MC3X1645, its
output grounds the gate of the L
2
MOSFET.
