LT6703HV-2/LT6703HV-3
Micropower, Low Voltage
Comparator with
400mV Reference
DESCRIPTION
FEATURES
TheLT®6703-2/LT6703-3/LT6703HV-2/LT6703HV-3com-
bine a micropower, low voltage comparator with a 400mV
reference in a tiny DFN package. Operating with supplies
from1.4Vupto18V,thesedevicesdrawonly6.5μA,making
them ideal for low voltage system monitoring. Hysteresis
is included in the comparator, ensuring stable operation.
n
Internal 400mV Reference
n
Total Threshold Error: ±±1.25 Maꢀ at .2ꢁ°
n
Wide Supply Range: ±14V to ±8V
Input and Output Operate to 36V
n
n
Specified for –40ꢁ° to ±.2ꢁ° Temperature Range
n
Low Quiescent Current: 6.5μA Typ at 5V
n
Internal Hysteresis: 6.5mV Typ
The comparator has one input available externally while
the other input is connected internally to the reference.
The comparator output is open collector and the output
load can be referred to any voltage up to 18V (36V for
LT6703HV) independent of supply voltage. The output
stage has a guaranteed current sink capability of more
than 5mA over temperature.
n
Low Input Bias Current: 10nA Max
Over-The-Top® Input also Includes Ground
n
n
Open-Collector Output Allows Level Translation
Choice of Input Polarities: LT6703-2/LT6703-3/
LT6703HV-2/LT6703HV-3
Available in 2mm × 2mm DFN and
n
n
Low Profile (1mm) SOT-23 (ThinSOT™) Packages
The two versions of this part differ by the polarity of the
available comparator input. The LT6703-2/LT6703HV-2
has an inverting input and the LT6703-3/LT6703HV-3 has
a noninverting input. Both versions are offered in com-
mercial, industrial and automotive temperature ranges.

Note ±: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note .: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 3: The inputs are protected by ESD diodes to the ground pin. If the
input voltage exceeds –0.3V below ground, the input current should be
limited to less than 10mA.

APPLICATIONS INFORMATION
TheLT6703-2/LT6703-3/LT6703HV-2/LT6703HV-3devices
are micropower comparators with a built-in 400mV refer-
ence. Features include wide supply voltage range (1.4V to
18V), Over-The-Top input and output range, 2% accurate
rising input threshold voltage and 6.5mV typical built-in
hysteresis.
Internal Reference
Eachcomparatorhasoneinputavailableexternally.Thetwo
versions of the part differ by the polarity of the available
input(i.e.,invertingornoninverting).Theothercomparator
input is connected internally to the 400mV reference. The
risinginputthresholdvoltageofthecomparatorisdesigned
to be equal to that of the reference (i.e., ≈400mV). The
reference voltage is established with respect to the device
GND connection.

APPLICATIONS INFORMATION
°omparator Input
Power Supplies
The comparator input can range from ground to 18V (36V
for LT6703HV), regardless of the supply voltage used. The
typical input current for inputs well above the threshold
(i.e., >800mV) is a few pA leaking into the input. With
decreasing input voltage, a small bias current begins
to be drawn out of the input, reaching a few nA when at
ground potential. The input may be forced 100mV below
groundwithoutcausinganimproperoutput, thoughsome
additional bias current will begin to flow from the ESD
input protection diode. Inputs driven further negative than
100mV below ground will not cause damage provided the
current is limited to 10mA.
The comparator circuitry operates from a single 1.4V
to 18V supply. A minimum 0.1μF bypass capacitor is
required between the V pin and GND. When an output
S
load is connected to the supply rail near the part and the
outputissinkingmorethan5mA,a1μFbypasscapacitoris
recommended. In instances where the supply is relatively
“soft” (such as with small batteries) and susceptible to
load steps, an additional 47Ω series decoupling resistor
can further improve isolation of supply transients from
the V pin.
S
°omparator Output
The comparator output is open collector and capable of
sinking 40mA typical. Load currents are directed out of
the GND pin of the part. The output off-state voltage may
range between –0.3V and 18V (36V for LT6703HV) with
respect to ground, regardless of the supply voltage used.
When the output high state bias voltage is above 18V, a
100kminimumpull-upresistorisrequiredandnototalload
capacitor greater than 100nF should be used. If the output
high state is above 18V, caution has to be taken to prevent
a short from the output directly to the bias voltage, even
if the output is in the off state. As with any open-collector
device, the outputs of multiple comparators may be tied
together to implement wire-AND logic functions.
