These comparators are optimized for low power 1.8V,
single-supply applications with greater than rail-to-rail
input operation. The internal input hysteresis eliminates
output switching due to internal input noise voltage,
reducing current draw. The open-drain output of the
MCP6566/6R/6U/7/9 family requires a pull up resistor
and it supports pull-up voltages above and below VDD
which can be used to level shift. The output toggle
frequency can reach a typical of 4 MHz (typical) while
limiting supply current surges and dynamic power
consumption during switching.

Power Supply (VSS and VDD)
The positive power supply pin (VDD) is 1.8V to 5.5V
higher than the negative power supply pin (VSS). For
normal operation, the other pins are at voltages
between VSS and VDD.
Typically, these parts are used in a single (positive)
supply configuration. In this case, VSS is connected to
ground and VDD is connected to the supply. VDD will
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the VDD pin. These can share a
bulk capacitor with nearby analog parts (within
100 mm), but it is not required.

APPLICATIONS INFORMATION
The MCP6566/6R/6U/7/9 family of open-drain output
comparators are fabricated on Microchip’s state-ofthe-art CMOS process. They are suitable for a wide
range of high speed applications requiring low power
consumption.
4.1
Comparator Inputs
4.1.1
NORMAL OPERATION
The input stage of this family of devices uses two
differential input stages in parallel. This configuration
provides three regions of operation, one operates at
low input voltages, one at high input voltages, and one
at mid input voltage. With this topology, the input
voltage range is 0.3V above VDD and 0.3V below VSS,
while providing low offset voltage through out the
common mode range. The input offset voltage is
measured at both VSS - 0.3V and VDD + 0.3V to ensure
proper operation.

Input Voltage (10 mV/div)
Output Voltage (V)
The MCP6566/6R/6U/7/9 family has internally-set
hysteresis VHYST that is small enough to maintain input
offset accuracy and large enough to eliminate output
chattering caused by the comparator’s own input noise
voltage ENI. Figure 4-1 depicts this behavior. Input
offset voltage (VOS) is the center (average) of the
(input-referred) low-high and high-low trip points. Input
hysteresis voltage (VHYST) is the difference between
the same trip points.
4.1.2
INPUT VOLTAGE AND CURRENT
LIMITS
The ESD protection on the inputs can be depicted as
shown in Figure 4-2. This structure was chosen to
protect the input transistors, and to minimize input bias
current (IB). The input ESD diodes clamp the inputs
when they try to go more than one diode drop below
VSS. They also clamp any voltages that go too far
above VDD; their breakdown voltage is high enough to
allow normal operation, and low enough to bypass ESD
events within the specified limits.

Simplified Analog Input ESD
In order to prevent damage and/or improper operation
of these amplifiers, the circuits they are in must limit the
currents (and voltages) at the VIN+ and VIN– pins (see
Section 1.1 “Maximum Ratings*” at the beginning of
Section 1.0 “Electrical Characteristics”). Figure 4-3
shows the recommended approach to protecting these
inputs. The internal ESD diodes prevent the input pins
(VIN+ and VIN–) from going too far below ground, and
the resistors R1 and R2 limit the possible current drawn
out of the input pin. Diodes D1 and D2 prevent the input
pin (VIN+ and VIN–) from going too far above VDD.
When implemented as shown, resistors R1 and R2 also
limit the current through D1 and D2.

It is also possible to connect the diodes to the left of the
resistors R1 and R2. In this case, the currents through
the diodes D1 and D2 need to be limited by some other
mechanism. The resistor then serves as in-rush current
limiter; the DC current into the input pins (VIN+ and
VIN–) should be very small.
4.3.1
NON-INVERTING CIRCUIT
Figure 4-4 shows a non-inverting circuit for singlesupply applications using just two resistors. The
resulting hysteresis diagram is shown in Figure 4-5.
A significant amount of current can flow out of the
inputs when the common mode voltage (VCM) is below
ground (VSS); see Figure 4-3. Applications that are
high impedance may need to limit the useable voltage
range.

PHASE REVERSAL
The MCP6566/6R/6U/7/9 comparator family uses
CMOS transistors at the input. They are designed to
prevent phase inversion when the input pins exceed
the supply voltages. Figure 2-3 shows an input voltage
exceeding both supplies with no resulting phase
inversion.
4.2
R1
Externally Set Hysteresis
Greater flexibility in selecting hysteresis (or input trip
points) is achieved by using external resistors.
Hysteresis reduces output chattering when one input is
slowly moving past the other. It also helps in systems
where it is best not to cycle between high and low
states too frequently (e.g., air conditioner thermostatic
control). Output chatter also increases the dynamic
supply current.

Open-Drain Output
The open-drain output is designed to make level-shifting and wired-OR logic easy to implement. The output
stage minimizes switching current (shoot-through
current from supply-to-supply) when the output
changes state. See Figures 2-15, 2-18, 2-35 and 2-36,

for the circuit shown in Figure 4-6, R2 and R3 can be
simplified to the Thevenin equivalent circuit with
respect to VDD, as shown in Figure 4-8.
VPU
VDD
With this family of comparators, the power supply pin
(VDD for single supply) should have a local bypass
capacitor (i.e., 0.01 µF to 0.1 µF) within 2 mm for good
edge rate performance.
4.5
Capacitive Loads
Reasonable capacitive loads (e.g., logic gates) have
little impact on propagation delay (see Figure 2-32).
The supply current increases with increasing toggle
frequency (Figure 2-20), especially with higher
capacitive loads. The output slew rate and propogation
delay performance will be reduced with higher
capacitive loads.

PCB Surface Leakage
4.7
In applications where low input bias current is critical,
PCB (Printed Circuit Board) surface leakage effects
need to be considered. Surface leakage is caused by
humidity, dust or other contamination on the board.
Under low humidity conditions, a typical resistance
between nearby traces is 1012Ω. A 5V difference would
cause 5 pA of current to flow. This is greater than the
MCP6566/6R/6U/7/9 family’s bias current at +25°C
(1 pA, typical).
The easiest way to reduce surface leakage is to use a
guard ring around sensitive pins (or traces). The guard
ring is biased at the same voltage as the sensitive pin.
An example of this type of layout is shown in
Figure 4-9.
IN-
IN+
VSS
When designing the PCB layout it is critical to note that
analog and digital signal traces are adequately
separated to prevent signal coupling. If the comparator
output trace is at close proximity to the input traces
then large output voltage changes from, VSS to VDD or
visa versa, may couple to the inputs and cause the
device output to oscillate. To prevent such oscillation,
the output traces must be routed away from the input
pins. The SC70-5 and SOT-23-5 are relatively immune
because the output pin OUT (pin 1) is separated by the
power pin VDD/VSS (pin 2) from the input pin +IN (as
long as the analog and digital traces remain separated
through out the PCB). However, the pinouts for the dual
and quad packages (SOIC, MSOP, TSSOP) have OUT
and -IN pins (pin 1 and 2) close to each other. The
recommended layout for these packages is shown in

Inverting Configuration (Figures 4-6 and 4-9):
a) Connect the guard ring to the non-inverting
input pin (VIN+). This biases the guard ring
to the same reference voltage as the
comparator (e.g., VDD/2 or ground).
b) Connect the inverting pin (VIN–) to the input
pad without touching the guard ring.
Non-inverting Configuration (Figure 4-4):
a) Connect the non-inverting pin (VIN+) to the
input pad without touching the guard ring.
b) Connect the guard ring to the inverting input
pin (VIN–).

Recommended Layout.
Unused Comparators
An unused amplifier in a quad package (MCP6569)
should be configured as shown in Figure 4-11. This
circuit prevents the output from toggling and causing
crosstalk. It uses the minimum number of components
and draws minimal current (see Figure 2-15 and
Figure 2-15).

Typical Applications
4.9.1
4.9.3
PRECISE COMPARATOR
Some applications require higher DC precision. An
easy way to solve this problem is to use an amplifier
(such as the MCP6291) to gain-up the input signal
before it reaches the comparator. Figure 4-12 shows
an example of this approach.
BISTABLE MULTI-VIBRATOR
A simple bistable multi-vibrator design is shown in
Figure 4-14. VREF needs to be between the power
supplies (VSS = GND and VDD) to achieve oscillation.
The output duty cycle changes with VREF.

WINDOWED COMPARATOR
Figure 4-13 shows one approach to designing a
windowed comparator. The AND gate produces a logic
‘1’ when the input voltage is between VRB and VRT
(where VRT > VRB).
