4.2
Negative Going VDD Transients
The minimum pulse width (time) required to cause a
reset may be an important criteria in the implementa-
tion of a Power-on Reset (POR) circuit. This time is
referred to as transient duration, defined as the amount
of time needed for these supervisory devices to
respond to a drop in VDD. The transient duration time is
dependant on the magnitude of VTRIP – VDD. Generally
speaking, the transient duration decreases with
increases in VTRIP – VDD.
Figure 4-3 shows a typical transient duration vs. reset
comparator overdrive for which the MCP111/112 will
not generate a reset pulse. It shows that the farther
below the trip point the transient pulse goes, the
duration of the pulse required to cause a reset gets
shorter. Figure 2-18 shows the transient response
characteristics for the MCP111/112.
A 0.1 µF bypass capacitor, mounted as close as
possible to the VDD pin, provides additional transient
immunity (refer to Figure 4-1).

Example of Typical
Transient Duration Waveform.
4.3
Effect of Temperature on Time-out
Period (tRPU)
The time-out period (t
RPU) determines how long the
device remains in the reset condition. This is affected
by both V
DD and temperature. The graph shown in
Figures 2-22, 2-23 and 2-24 show the typical response
for different V
DD values and temperatures.
4.4
Using in PICmicro®
Microcontroller ICSP™
Applications (MCP111 only)
Figure 4-4 shows the typical application circuit for using
the MCP111 for voltage supervisory function when the
PICmicro microcontroller will be programmed via the
In-Circuit
Serial
Programming™
(ICSP)
feature. Additional information is available in TB087,
“Using Voltage Supervisors with PICmicro® Microcon-
troller Systems which Implement In-Circuit Serial
Programming™”, DS91087.
