addition of C DLY . For systems with extremely fast
power supply rise times (<500 ns) it is recommended
that the RC DLY time constant be greater than 5.0 m s.
V th(MPU) is the microprocessor reset input threshold.

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 CC crosses the comparator threshold
(Figure 4). An increase of the lower threshold D V th(lower) will be observed due to I in which is typically 340 m A at
4.59 V. The equations are accurate to ± 10% with R H less than 150 W and R L between 1.5 k W and 10 k W .
