DESCRIPTION

Micropower, Low Voltage

Comparator with

400mV Reference

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.
