FEATURES
DESCRIPTION
Micropower, Low Voltage
Comparator with
400mV Reference
The LT6703-2/LT6703-3/LT6703HV-2/LT6703HV-3 com-
bine a micropower, low voltage comparator with a 400mV
reference in a tiny DFN package. Operating with supplies
from 1.4V up to 18V, these devices draw only 6.5μA, making
them ideal for low voltage system monitoring. Hysteresis
is included in the comparator, ensuring stable operation.
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.
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.
