●● Open-Drain Output Versions Available
(MAX9016/MAX9018/MAX9020)
●● Crowbar-Current-Free Switching
●● Internal 4mV Hysteresis for Clean Switching
●● No Phase Reversal for Overdriven Inputs
●● Dual Versions in Space-Saving 8-Pin SOT23 Package
The single MAX9015/MAX9016 and dual MAX9017–
MAX9020 nanoPower comparators in space-saving
SOT23 packages feature Beyond-the-Rails™ inputs and
are guaranteed to operate down to 1.8V. The A-grade
packages feature an on-board 1.236V ±1% reference,
while the B-grade packages feature a 1.24V ±1.75%
reference. An ultra-low supply current of 0.85μA (MAX9019/
MAX9020), 1μA (MAX9015/MAX9016), or 1.2μA (MAX9017/
MAX9018) makes this product family of comparators ideal
for all 2-cell battery monitoring/management applications.
The unique design of the devices output stage limits supplycurrent surges while switching, which virtually eliminates
the supply glitches typical of many other comparators.
This design also minimizes overall power consumption
under dynamic conditions. The MAX9015/MAX9017/
MAX9019 have a push-pull output stage that sinks and
sources current. Large internal output drivers allow railto-rail output swing with loads up to 6mA. The MAX9016/
MAX9018/MAX9020 have an open-drain output stage
that makes them suitable for mixed-voltage system
design. All devices are available in the ultra-small 8-pin
SOT23 package.

Note 1: All devices are 100% tested at TA = +25°C. Specifications over temperature (TA = TMIN to TMAX) are guaranteed by design,
not production tested.
Note 2: VOS is defined as the center of the hysteresis band at the input.
Note 3: The hysteresis-related trip points are defined as the edges of the hysteresis band, measured with respect to the center of the
band (i.e., VOS) (Figure 1).
Note 4: Specified with an input overdrive (VOVERDRIVE) of 100mV, and a load capacitance of CL = 15pF. VOVERDRIVE is defined
above and beyond the offset voltage and hysteresis of the comparator input.
Note 5: High current traces should not be routed in the vicinity of or below MAX9018. There is a chance of voltage reference being
overloaded resulting in drop of output voltage.

Detailed Description
Output Stage Circuitry
The MAX9015–MAX9018 feature an on-board 1.24V
±0.5% (±1.45% for the B grade) reference, yet draw
an ultra-low supply current. The MAX9019/MAX9020
(duals without reference) consume just 850nA of supply
current. All devices are guaranteed to operate down to
1.8V supply. Their common-mode input voltage range
extends 200mV beyond-the-rails. An internal 4mV
hysteresis ensures clean output switching, even
with slow-moving input signals. Large internal output
drivers swing rail-to-rail with up to ±6mA loads (MAX9015/
MAX9017/MAX9019).
The output stage employs a unique design that
minimizes supply-current surges while switching, which
virtually eliminates the supply glitches typical of many
other comparators. The MAX9015/MAX9017/MAX9019
have a push-pull output stage that sinks as well as sources
current. The MAX9016/MAX9018/MAX9020 have an
open-drain output stage that can be pulled beyond VCC
up to 5.5V above VEE. These open-drain versions are
ideal for implementing wire-ORed output logic functions.
Input Stage Circuitry
The input common-mode voltage ranges extend from
VEE - 0.2V to VCC + 0.2V. These comparators operate
at any differential input voltage within these limits. Input
bias current is typically ±150pA at the trip point, if the
input voltage is between the supply rails. Comparator
inputs are protected from overvoltage by internal ESD
protection diodes connected to the supply rails. As the
input voltage exceeds the supply rails, these ESD protection diodes become forward biased and begin to conduct
increasing input bias current (see the Input Bias Current
vs. Input Bias Voltage graph in the Typical Operating
Characteristics).
The devices feature a unique break-before-make output
stage capable of driving ±8mA loads rail-to-rail. Many
comparators consume orders of magnitude more current
during switching than during steady-state operation.
However, with this device family of comparators, the supplycurrent change during an output transition is extremely
small. In the Typical Operating Characteristics, the Supply
Current vs. Output Transition Frequency graphs show the
minimal supply-current increase as the output switching
frequency approaches 1kHz. This characteristic reduces
the need for power-supply filter capacitors to reduce
glitches created by comparator switching currents. In
battery-powered applications, this characteristic results in
a substantial increase in battery life.
Reference (MAX9015–MAX9018)
The MAX9015–MAX9018s’ internal +1.24V reference
has a typical temperature coefficient of 40ppm/°C over
the full -40°C to +85°C temperature range. The reference
is a very-low-power bandgap cell, with a typical 35kΩ
output impedance. REF can source and sink up to 100nA
to external circuitry. For applications needing increased
drive, buffer REF with a low input-bias current op amp
such as the MAX4162. Most applications require no
REF bypass capacitor. For noisy environments or fast
transients, connect a 1nF to 10nF ceramic capacitor from
REF to GND.
Applications Information
Low-Voltage, Low-Power Operation
The MAX9015–MAX9020 are ideally suited for use with
most battery-powered systems. Table 1 lists a variety

Internal Hysteresis
The hysteresis in a comparator creates two trip points:
one for the rising input voltage (VTHR) and one for the
falling input voltage (VTHF) (Figure 1). The difference
between the trip points is the hysteresis (VHB). When
the comparator’s input voltages are equal, the hysteresis
effectively causes one comparator input to move quickly
past the other, thus taking the input out of the region
where oscillation occurs. Figure 1 illustrates the case in
which the comparator’s inverting input has a fixed voltage
applied, and the noninverting input is varied. If the inputs
were reversed, the figure would be the same, except with
an inverted output.
THRESHOLDS
IN+
Many comparators oscillate in the linear region of operation because of noise or undesired parasitic feedback.
Oscillations can occur when the voltage on one input is
equal or very close to the voltage on the other input. The
devices have internal 4mV hysteresis to counter parasitic
effects and noise.

The MAX9015/MAX9017/MAX9019 feature a built-in
4mV hysteresis band (VHB). Additional hysteresis can
be generated with three resistors using positive feedback (Figure 2). Use the following procedure to calculate
resistor values:
1) Select R3. Input bias current at IN_+ is less than 2nA,
so the current through R3 should be at least 0.2μA to
minimize errors caused by input bias current. The current through R3 at the trip point is (VREF - VOUT)/R3.
Considering the two possible output states in solving
for R3 yields two formulas: R3 = VREF/IR3 or R3 =
(VCC - VREF)/IR3. Use the smaller of the two resulting
resistor values. For example, when using the MAX9017
(VREF = 1.24V) and VCC = 5V, and if we choose IR3
= 0.2μA, then the two resistor values are 6.2MΩ and
19MΩ. Choose a 6.2MΩ standard value for R3.

(Open-Drain Outputs)
The MAX9016/MAX9018/MAX9020 feature a built-in 4mV
hysteresis band. These devices have open-drain outputs
and require an external pullup resistor (Figure 3). Additional
hysteresis can be generated using positive feedback, but
the formulas differ slightly from those of the MAX9015/
MAX9017/MAX9019. Use the following procedure to
calculate resistor values:
1) Select R3. Input bias current at IN_+ is less than 2nA,
so the current through R3 should be at least 0.2μA
to minimize errors caused by input bias current. The
current through R3 at the trip point is (VREF - VOUT)/
R3. Considering the two possible output states in solving
for R3 yields two formulas: R3 = VREF/IR3 or R3 =
[(VCC - VREF)/IR3] - R4. Use the smaller of the two
resulting resistor values. For example, when using
the MAX9018 (VREF = 1.24V) and VCC = 5V, and
if we choose IR3 = 0.2μA, and R4 = 1MΩ, then the
two resistor values are 6.2MΩ and 18MΩ. Choose a

The devices’ ultra-low supply current typically requires
no power-supply bypass capacitors. However, when the
supply has high output impedance, long lead lengths or
excessive noise, or fast transients, bypass VCC to VEE
with a 0.1μF capacitor placed as close to the VCC pin as
possible. Minimize signal trace lengths to reduce stray
capacitance. Use a ground plane and surface-mount
components for best performance. If REF is decoupled,
use a low-leakage ceramic capacitor. High traces should
not be routed in the vicinity of or below MAX9018. There
is a chance of voltage reference being overloaded resulting
in drop of output voltage.

The MAX9018 is ideal for window detectors (undervoltage/overvoltage detectors). Figure 4 shows a window
detector circuit for a single-cell Li+ battery with a 2.9V
end-of-life charge, a peak charge of 4.2V, and a nominal
value of 3.6V. Choose different thresholds by changing
the values of R1, R2, and R3. OUTA provides an activelow undervoltage indication, and OUTB provides an
active-low overvoltage indication. ANDing the two opendrain outputs provides an active-high, power-good signal.
The design procedure is as follows:
1) Select R1. The input bias current into INB- is normally less than 2nA, so the current through R1 should
exceed 100nA for the thresholds to be accurate. In this
example, choose R1 = 1.24MΩ (1.24V/1μA).
2) Calculate R2 + R3. The overvoltage threshold should
be 4.2V when VIN is rising. The design equation is as
follows:

Zero-Crossing Detector
Figure 5 shows a zero-crossing detector application.
The MAX9015/MAX9016/MAX9019/MAX9020s’ inverting
input is connected to ground, and its noninverting input
is connected to a 100mVP-P signal source. As the signal
at the noninverting input crosses zero, the comparator’s
output changes state.

Logic-Level Translator
The open-drain comparators can be used to convert 5V
logic to 3V logic levels. The MAX9020 can be powered
by the 5V supply voltage, and the pullup resistor for the
MAX9020’s open-drain output is connected to the 3V
supply voltage. This configuration allows the full 5V logic
swing without creating overvoltage on the 3V logic inputs.
For 3V to 5V logic-level translations, connect the 3V
supply voltage to VCC and the 5V supply voltage to the
pullup resistor.
