Comparator hysteresis can be increased with the addition of resistor RH. The hysteresis equation has been simplified and does not account for the change of input current
Iin as Vin crosses the comparator threshold (Figure 8). An increase of the lower threshold Vth(lower) will be observed due to Iin which is typically 10 A at 4.3 V. The
equations are accurate to
±10% with RH less than 1.0 k and RL 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 MC3X164–5, its
output grounds the gate of the L2 MOSFET.
