Maxim MAX9018AEKA-T Sot23, dual, precision, 1.8v, nanopower comparators with/without reference Datasheet

19-2874; Rev 2; 12/09
SOT23, Dual, Precision, 1.8V, Nanopower
Comparators With/Without Reference
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 Agrade 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 the MAX9015–
MAX9020 family of comparators ideal for all 2-cell battery monitoring/management applications.
The unique design of the MAX9015–MAX9020 output
stage limits supply-current 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 rail-to-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.

Comparators With/Without Reference
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 slowmoving 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).
Output Stage Circuitry
The MAX9015–MAX9020 feature a unique breakbefore-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 the MAX9015–
MAX9020 family of comparators, the supply-current
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 of
battery types, capacities, and approximate operating

Detailed Description
MAX9015–MAX9020
SOT23, Dual, Precision, 1.8V, Nanopower
Comparators With/Without Reference
Internal Hysteresis
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 MAX9015–MAX9020 have internal 4mV hysteresis to counter parasitic effects and noise.
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.

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.
2) Choose the hysteresis band required (VHB). For this
example, choose 50mV.
3) Calculate R1 according to the following equation:

(MAX9016/MAX9018/MAX9020)
(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 6.2MΩ standard value for R3.

Board Layout and Bypassing
The MAX9015–MAX9020 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.

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 V IN is rising. The design

For this example, choose a 499kΩ standard value 1%
resistor.
4) Calculate R3:
R3 = (R2 + R3) - R2
= 2.95MΩ - 546kΩ
= 240MΩ
5) Verify the resistor values. The equations are as follows, evaluated for the above example:
Overvoltage threshold:
VOTH = (VREF + VHB ) x
= (1.24MΩ + 2.95MΩ) x
= 546kΩ

Window Detector
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 active-low undervoltage indication, and OUTB provides an active-low overvoltage indication. ANDing the
two open-drain outputs provides an active-high, powergood signal.
The design procedure is as follows:
5V
VUTH = (VREF − VHB ) x
(R1 + R2 + R3)
= 2.97V
(R1 + R2)
where the internal hysteresis band, VHB, is 4mV.
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.
