• Precision monitoring options of:
- 1.90V, 2.32V, 2.63V, 2.90V, 2.93V, 3.08V,
4.38V and 4.63V
• Resets microcontroller in a power-loss event
• Active-low VOUT pin:
- MCP111 active-low, open-drain
- MCP112 active-low, push-pull
• Available in SOT23-3, TO-92 and SC70 packages
• Temperature Range:
- Extended: –40°C to +125°C
(except MCP1XX-195)
- Industrial: –40°C to +85°C (MCP1XX-195 only)
The MCP111/112 are voltage-detecting devices
designed to keep a microcontroller in reset until the
system voltage has reached, and 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 a safe operating level. The MCP111 and
MCP112 are available in eight different trip voltages.

The MCP111 has an open-drain output with an activelow pin (VOUT). This device will assert VOUT when the
voltage on the VDD pin is below the trip-point voltage.
The MCP112 has a push-pull output and will assert an
active-low signal (VOUT pin) when the voltage on the
VDD pin is below the trip-point voltage.
During operation, the output (VOUT) remains at a logichigh as long as VDD is greater than the specified
threshold voltage. When VDD falls below the voltage
trip point, VOUT is driven low.

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

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 POR circuit. This time is referred to as
transient duration and is 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.
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 4-3 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 cap mounted as close as possible to
the VDD pin provides additional transient immunity
(refer to Figure 4-1).
