A time delayed reset can be accomplished with the
addition of CDLY. For systems with extremely fast
power supply rise times (<500 ns) it is recommended
that the RCDLY time constant be greater than 5.0
μ
s.
Vth(MPU) is the microprocessor reset input threshold.

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 VCC crosses the comparator threshold
(Figure 4). An increase of the lower threshold
Vth(lower) will be observed due to Iin which is typically 340
μ
A at
4.59 V. The equations are accurate to
±
10% with RH less than 150
and RL between 1.5 k
and 10 k
.
