APPLICATIONS

Battery management/monitoring

Power supply detection

Window comparators

Threshold detectors/discriminators

Microprocessor systems

The ADCMP391 features a common-mode input voltage range

of 200 mV beyond rails, an offset voltage of 1 mV typical across

the full common-mode range, and a UVLO monitor. In addition,

the design of the comparator allows a defined output state upon

power-up. The comparator generates a logic low output if the

supply voltage is less than the UVLO threshold.

GENERAL DESCRIPTION

The ADCMP391 is a single, rail-to-rail input, low power

comparator ideal for use in general-purpose applications. The

device operates from a single supply voltage of 2.3 V to 5.5 V

and draws a minimal amount of current. The ADCMP391

consumes only 18.6 µA of supply current. The low voltage and

low current operation of the ADCMP391 makes it ideal for

battery-powered systems.

The ADCMP391 is available in an 8-lead, narrow body SOIC

package. The ADCMP391 is specified to operate over the

extended temperature range of −40°C to +125°C.
