Description
–
The MCP111/112 are voltage-detecting devices
designed to keep a microcontroller in reset until the
system voltage has stabilized at the appropriate level
for reliable system operation. These devices also
operate as protection from brown-out conditions when
the system supply voltage drops below the specified
threshold voltage level. Eight different trip voltages are
available.

This specification allows this device to be used in PICmicro® microcontroller applications that require the In-Circuit
Serial Programming™ (ICSP™) feature (see device-specific programming specifications for voltage requirements).
This specification DOES NOT allow a continuous high voltage to be present on the open-drain output pin (VOUT). The
total time that the VOUT pin can be above the maximum device operational voltage (5.5V) is 100 sec. Current into the
VOUT pin should be limited to 2 mA. It is recommended that the device operational temperature be maintained between
0°C to 70°C (+25°C preferred). For additional information, please refer to Figure 2-28.
This parameter is established by characterization and is not 100% tested.

APPLICATION INFORMATION
4.1
For many of today’s microcontroller applications, care
must be taken to prevent low-power conditions that can
cause many different system problems. The most
common causes are brown-out conditions, where the
system supply drops below the operating level momentarily. The second most common cause is when a slowly
decaying power supply causes the microcontroller to
begin executing instructions without sufficient voltage to
sustain SRAM, thus producing indeterminate results.
Figure 4-1 shows a typical application circuit.
VDD

µF
VTRIP Operation
The voltage trip point (VTRIP) is determined on the falling
edge of VDD. The actual voltage trip point (VTRIPAC) will
be between the minimum trip point (VTRIPMIN) and the
maximum trip point (VTRIPMAX). There is a hysteresis on
this trip point to remove any “jitter” that would occur on
the VOUT pin when the device VDD is at the trip point.
Figure 4-2 shows the state of the VOUT pin as
determined by the VDD voltage. The VTRIP specification
is for falling VDD voltages. When the VDD voltage is
rising, the VOUT pin will not be driven high until VDD is at
VTRIP + VHYS.

4.2
Negative Going VDD Transients
The minimum pulse width (time) required to cause a
reset may be an important criteria in the implementation 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).
4.3
Effect of Temperature on Time-out
Period (tRPU)
The time-out period (tRPU) determines how long the
device remains in the reset condition. This is affected
by both VDD and temperature. The graph shown in
Figures 2-22, 2-23 and 2-24 show the typical response
for different VDD values and temperatures.

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

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
