LT6703 - Micropower, Low Voltage Comparator with 400mV Reference

The LT6703-2/LT6703-3/LT6703HV-2/LT6703HV-3 combine 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 commercial, industrial and automotive temperature ranges.
