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 D V th(lower) will be observed due to I in which is typically 10 m A at 4.3 V. The
equations are accurate to ± 10% with R H less than 1.0 k W and R L between 4.3 k W and 43 k W .

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
1.2 V ref
output grounds the gate of the L 2 MOSFET.
