GENERAL DESCRIPTION

ADCMP343

The ADCMP341/ADCMP343 combine two low power, low

voltage comparators with a 400mV reference in the 5-lead

SOT-23 package. Operating within a supply range of 1.7V to

5.5V, the devices only draw 6.5µA typical, making them ideal

for low voltage system monitoring and portable applications.

Hysteresis is determined using three resistors in a string

configuration with the upper and lower tap points connected to

the INA_U and INA_L pins of each comparator respectively.

The state of the comparators output internally selects which pin

is connected to the comparator inputs. So a change of state in

the comparator output will result in one of the inputs being

switched in to the comparator and the other being switched

out. This will provide the user with a fully flexible and simple

method of setting the hysteresis. Although there are two pins

available on each comparator, there is only actually one input

available externally at any one time, the other inputs are

connected internally to the reference.

The comparator outputs are open drain with the output stage

sinking capability guaranteed greater than 5mA over

temperature. The ADCMP341 have noninverting inputs and

the ADCMP343 have inverting inputs. Available in

commercial, industrial and automotive temperature ranges.
