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. Ei gh t different trip v ol t ag es are
available.

Note 1: Trip point is ±1.5% from typical value.

3: 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.

4.0 APPLICATION INFORMATION
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 momen-
tarily . 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 circ uit.
FIGURE 4-1: Typic al App li ca tio n Circui t.
4.1 VTRIP Operation
The volt age trip point ( VTRIP) is determined on the falling
edge of VDD. The a ctual vol tage tr ip poi nt (V TRIPAC) will
be between the minimum trip point (VTRIPMIN) and the
maximum trip point (VTRIPMAX). There is a hyst eres is 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 implementa-
tion of a Power-on Reset (POR) circuit. This time is
referred to as trans ient duration, de fined as the amount
of time needed for these supervisory devices to
respond to a drop in VDD. The tran sient du ration t ime is
dependa nt on the magnitude of V TRIP – VDD. Gener ally
speaking, the transient duration decreases with
increases in VTRIP – VDD.
Figur e 4- 3 shows a t ypical t ransient duratio n 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
characteris ti cs 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).
FIGURE 4-3: Example of Typical
Transient Duration Waveform.
4.3 Effect of Temperature on T ime-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
Figur es 2-22, 2-23 and 2-24 sho w the ty pical respo nse
for different VDD 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 Vo ltage Supervisors with PICmicro® Micr ocon-
troller Systems which Implement In-Circuit Serial
Programming™”, DS91087.
