The MIC2774 is a dual power supply supervisor that
provides undervoltage monitoring, manual reset
capability, and power-on reset generation in a compact
5-pin SOT-23 package. Features include two
undervoltage detectors, one fixed and one adjustable,
and a choice of reset outputs. One undervoltage
detector compares VDD against a fixed threshold. Ten
factory-programmed thresholds are available. The
second, user-adjustable input is compared against a
300 mV reference. This low reference voltage allows
for the monitoring of voltages lower than those
supported by previous supervisor ICs.
Applications
• Monitoring Processor ASIC or FPGA Core and
I/O Voltages
• PDAs, Handheld PCs
• Embedded Controllers
• Telecommunications Systems
• Power Supplies
• Wireless/Cellular Systems
• Networking Hardware
The reset outputs are asserted at power-on and at any
time either voltage drops below the programmed
threshold voltage and remains asserted for 140 ms
(min.) after they subsequently rise back above the
threshold boundaries. Manual reset functionality can
be provided by a switch connected between ground
and the /MR input. A wide choice of voltage thresholds
provides for a variety of supply voltages and
tolerances. Hysteresis is included to prevent chattering
due to noise. Typical supply current is a low 3.5 µA.

FUNCTIONAL DESCRIPTION
3.1
IN, Undervoltage Detector Input
The voltage present at the IN pin is compared to the
internal 300 mV reference voltage. A reset is triggered
if and when VIN falls below VREF. Typically, a resistor
divider is used to scale the input voltage to be
monitored such that VIN will fall below VREF as the
voltage being monitored falls below the desired
trip-point. Hysteresis is employed to prevent chattering
due to noise. The comparator on the IN pin is relatively
immune to very brief negative-going transients.
3.2
VDD Input
The VDD pin is both the power supply terminal and a
monitored input voltage. The voltage at this pin is
continually compared against the internal reference.
The trip-point at which a reset occurs is
factory-programmed. A reset is triggered if and when
VDD falls below the trip-point. Hysteresis is employed to
prevent chattering due to noise. The comparator on the
VDD input is relatively immune to very brief
negative-going transients.
DS20006527A-page 6
3.3
RST, /RST Reset Output
Typically, the MIC2774 is used to monitor the power
supplies of intelligent circuits such as microcontrollers
and microprocessors. By connecting the appropriate
reset output of an MIC2774 to the reset input of a µC or
µP, the processor will be properly reset at power-on,
power-down, and during brown-out conditions. In
addition, asserting /MR, the manual reset input, will
activate the reset function.
The reset output is asserted any time /MR is asserted,
or if VIN or VDD drops below the corresponding
threshold voltage. The reset output remains asserted
for tRST(min) after VIN and/or VDD subsequently return
above the threshold boundaries and/or /MR is
released. A reset pulse is also generated at power-on.
Hysteresis is included in the comparators to prevent
chattering of the output due to noise.
3.4
/MR, Manual Reset Input
The ability to initiate a reset via external logic or a
manual switch is provided in addition to the MIC2774’s
automatic supervisory functions. Driving the /MR input
to a logic low causes an immediate and unconditional
reset to occur. Assuming VIN and VDD are within
tolerance when /MR is released (returns high), the
reset output will be de-asserted no less than tRST later.
/MR may be driven by a logic signal or mechanical
switch. Typically, a momentary push-button switch is
connected such that /MR is shorted to ground when the
switch contacts close. Switch de-bouncing is
performed internally; the switch may be connected
directly between /MR and GND. /MR is internally pulled
up to VDD and may be left open if unused.

APPLICATION INFORMATION
4.1
Programming the Voltage
Threshold
Referring to the Typical Application Circuit, the voltage
threshold on the IN pin is calculated as follows:
EQUATION 4-1:
R1 + R2
V IH = V REF -------------------R2
Where:
VREF = 0.300V
In order to provide the additional criteria needed to
solve for the resistor values, the resistors can be
selected such that the two resistors have a given total
value; that is, R1 + R2 = RTOTAL. Imposing this
condition on the resistor values provides two equations
that can be solved for the two unknown resistor values.
A value such as 1 MΩ for RTOTAL is a reasonable
choice because it keeps quiescent current to a
generally acceptable level while not causing any
measurable errors due to input bias currents. The
larger the resistors, the larger the potential errors due
to input bias current (IIN). The maximum recommended
value of RTOTAL is 3 MΩ.
Applying this criteria and rearranging the VIH
expression to solve for the resistor values gives:
EQUATION 4-2:
R TOTAL V REF
R2 = -------------------------------------V IH
R1 = R TOTAL – R2
4.2
Application Example
Figure 4-1 illustrates a hypothetical MIC2774L-23
application in which the MIC2774L-23 is used to
monitor the core and I/O supplies of a
high-performance CPU or DSP. The core supply,
VCORE, in the example is 1.0V ±5%. The main power
rail and I/O voltage, VI/O, is 2.5V ±5%. As shown in
Figure 4-1, the MIC2774 is powered by VI/O. The
minimum value of VI/O is 2.5V – 5% = 2.375V; the
maximum is 2.5V + 5% = 2.625V. This is well within the
device’s supply range of 1.5V to 5.5V.
2022 Microchip Technology Inc.
Resistors R1 and R2 must be selected to correspond to
the VCORE supply of 1.0V. The goal is to ensure that the
core supply voltage is adequate to ensure proper
operation; i.e., VCORE ≥ (1.0V – 5%) = 0.950V. Because
there is always a small degree of uncertainty due to the
accuracy of the resistors, variations in the device’s
voltage reference, etc., the threshold will be set slightly
below this value. The potential variation in the
MIC2774’s voltage reference (VREF) is specified as
±1.5%. The resistors chosen will have their own
tolerance specifications. This example assumes the
use of 1% accurate resistors. The potential worst-case
error contribution due to input bias current can be
calculated once the resistor values are chosen. If the
guidelines above regarding the maximum total value of
R1 + R2 are followed, this error contribution will be very
small thanks to the MIC2774’s very low input bias
current.
To summarize, the various potential error sources are:
• Variation in VREF: specified at ±1.5%
• Resistor tolerance: chosen by designer (typically
≤±1%)
• Input bias current, IIN: calculated once resistor
values are known, typically very small
Taking the various potential error sources into account,
the threshold voltage will be set slight below the
minimum VCORE specification of 0.950V so that when
the actual threshold voltage is at its maximum, it will not
intrude into the normal operating range of VCORE. The
target threshold voltage will be set as follows:
Given that the total tolerance on VTH for the IN pin is
[VREF tolerance] + [resistor tolerance]
= ±1.5% + ±1% = ±2.5%,
and VTH(max) = VCORE(min),
then VCORE(min) = VTH + 2.5% VTH = 1.025 VTH,
therefore, solving for VTH results in
EQUATION 4-3:
V CORE MIN
0.950
V TH = ----------------------------- = ------------ = 0.9268V
1.025
1.025
Solving for R1 and R2 using this value for VTH and the
equations above yields:
R1 = 676.3 kΩ ≈ 673 kΩ
R2 = 323.7 kΩ ≈ 324 kΩ
The resulting circuit is shown in Figure 4-1.
DS20006527A-page 7
MIC2774
4.3
Input Bias Current Effects
Now that the resistor values are known, it is possible to
calculate the maximum potential error due to input bias
current, IIN. As shown in the Electrical Characteristics
table, the maximum value of IIN is 10 nA. Note that the
typical value is a much smaller 5 pA. The magnitude of
the offset caused by IIN is given by:

VERROR = ±1×10-8A × 2.189×105Ω
VERROR = ±2.189×10-3V
VERROR = ±2.189 mV
The typical error is about three orders of magnitude
lower than this—close to one microvolt. Generally, the
error due to input bias can be discounted. If it is to be
taken into account, simply adjust the target threshold
voltage downward by this amount and recalculate R1
and R2. The resulting value will be very close to
optimum. If accuracy is more important than the
quiescent current in the resistors, simply reduce the
value of RTOTAL to minimize offset errors.

The MIC2774 is inherently immune to very short
negative-going glitches. Very brief transients may
exceed the voltage thresholds without tripping the
output.
In general, as shown in Figure 4-3 and Figure 4-4, the
narrower the transient, the deeper the threshold
overdrive that the MIC2774 will ignore. The graphs
represent the typical allowable transient duration for a
given amount of threshold overdrive that will not
generate a reset.

Interfacing to Processors with
Bidirectional Reset Pins
Some microprocessors have reset signal pins that are
bidirectional, rather than input-only. The Motorola
68HC11 family is one example. Because the
MIC2774N’s output is open-drain, it can be connected
directly to the processor’s reset pin using only the
pull-up resistor normally required. See Figure 4-2.

Ensuring Proper Operation at Low
Supply
At VDD levels below 1.2V, the MIC2774’s reset output
cannot turn on sufficiently to produce a valid logic-low
on /RST. In this situation, circuits driven by /RST could
be allowed to float, causing undesired operation. In
most cases, however, it is expected that the circuits
driven by the MIC2774L will be similarly inoperative at
VDD ≤ 1.2V.
If a given application requires that /RST be valid below
VDD = 1.2V, this can be accomplished by adding a
pull-down resistor to the /RST output. A value of
100 kΩ is recommended because this is usually an
acceptable compromise of quiescent current and
pull-down current. The resistor’s value is not critical,
however. See Figure 4-5.
These statements also apply to the MIC2774H’s RST
output. That is, to ensure valid RST signal levels at VDD
< 1.2V, a pull-up resistor (as opposed to a pull-down)
should be added to the RST output. A value of 100 kΩ
is typical for this application, as well. See Figure 4-6.
