DESCRIPTION

The LT

LT6700HV-2/LT6700HV-3 combine two micropower, low

voltage comparators with a 400mV reference in a 6-lead

SOT-23 or 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 comparators, easing design requirements

to insure stable output operation.

The comparators each have one input available externally;

the other inputs are connected internally to the reference.

The comparator outputs are open collector and the output

load can be referred to any voltage up to 18V (36V for

LT6700HV), independent of supply voltage. The output

stage sinking capability is guaranteed to be greater than

5mA over temperature.

The three versions of this part differ by the polar-

ity of the available comparator inputs. The LT6700-1/

LT6700HV-1 has one inverting input and one noninvert-

ing input, making it suitable for use as a window com-

parator. The LT6700-2/LT6700HV-2 has two inverting

inputs and the LT6700-3/LT6700HV-3 has two nonin-

verting inputs. All versions are offered in commercial,

industrial and automotive temperature ranges.
