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 DVth(lower) will be observed due to Iin which is typically 10 mA at 4.3 V. The

equations are accurate to

±10% with RH less than 1.0 kW and RL between 4.3 kW and 43 kW.

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.
