General Description
–
The MCP102/103/121/131 are voltage supervisor
devices designed to keep a microcontroller in reset
until the system voltage has reached and stabilized at
the proper level for reliable system operation. The table
below shows the available features for these devices.

Applications
SOT23-3/SC-70
MCP102/121/131
• Ultra low supply current: 1.75 µA (steady state max.)
• Precision monitoring options of:
- 1.90V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V
and 4.63V

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 volitile memory (RAM), thus
producing indeterminate results. Figure 4-1 shows a
typical application circuit.
The MCP102/103/121/131 are voltage supervisor
devices designed to keep a microcontroller in reset
until the system voltage has reached and stabilized at
the proper 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.

Note 1: Resistor RPU may be required with the
MCP121 due to the open-drain output.
Resistor RPU may not be required with
the MCP131 due to the internal pull-up
resistor. The MCP102 and MCP103 do
not require the external pull-up resistor.
FIGURE 4-1:
Typical Application Circuit.
RST Operation
The RST output pin operation determines how the
device can be used, and indicates when the system
should be forced into reset. To accomplish this, an
internal voltage reference is used to set the voltage trip
point (VTRIP). Additionally, there is a hysteresis on this
trip point.
When the falling edge of VDD crosses this voltage
threshold, the reset power-down timer (TRPD) starts.
When this delay timer times out (TRPD), the RST pin is
forced low.
When the rising-edge of VDD crosses this voltage
threshold, the reset power-up timer (TRPU) starts.
When this delay timer times out (TRPU), the RST pin is
forced high, the reset power-up timer is active and
there is additional system current.
The actual voltage trip point (VTRIPAC) will be between
the minimum trip point (VTRIPMIN) and the maximum
trip point (VTRIPMAX). The hysteresis on this trip point
and the delay timer (TRPU) are to remove any “jitter”
that would occur on the RST pin when the device VDD
is at the trip point.
Figure 4-2 shows the waveform of the RST pin as determined by the VDD voltage, while Table 4-1 shows the
state of the RST pin. The VTRIP specification is for falling
VDD voltages. When the VDD voltage is rising, the RST
will not be driven high until VDD is at VTRIP + VHYS. Once
VDD has crossed the voltage trip point, there is also a
minimal delay time (TRPD) before the RST pin is driven
low.

MCP102/103/121/131
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.
Figure 4-3 shows a typical transient duration vs. reset
comparator overdrive, for which the MCP102/103/121/
131 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 2-32 shows the transient response
characteristics for the MCP102/103/121/131.
A 0.1 µF bypass capacitor, mounted as close as
possible to the VDD pin, provides additional transient
immunity (refer to Figure 4-1).

Reset Power-up Timer (tRPU)
Figure 4-4 illustrates the device current states. While
the system is powering down, the device has a low
current. This current is dependent on the device VDD
and trip point. When the device VDD rises through the
voltage trip point (VTRIP), an internal timer starts. This
timer consumes additional current until the RST pin is
driven (or released) high. This time is known as the
Reset Power-up Time (tRPU). Figure 4-4 shows when
tRPU is active (device consuming additional current).

EFFECT OF TEMPERATURE ON
RESET POWER-UP TIMER (TRPU)
The Reset Power-up timer time-out period (tRPU)
determines how long the device remains in the reset
condition. This is affected by both VDD and temperature.
Typical responses for different VDD values and
temperatures are shown in Figures 2-26, 2-27 and
2-28.

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.
Information contained in this publication regarding device
applications and the like is intended through suggestion only
