Hex Window Comparator with 1.5% Precision and 400mV

Reference

General Description

The LMV7231 is a 1.5% accurate Hex Window Comparator

which can be used to monitor power supply voltages. The

device uses an internal 400mV reference for the comparator

trip value. The comparator set points can be set via external

resistor dividers. The LMV7231 has 6 outputs (CO1-CO6)

that signal an under-voltage or over-voltage event for each

power supply input. An output (AO) is also provided to signal

when any of the power supply inputs have an over-voltage or

under-voltage event. This ability to signal an under-voltage or

over-voltage event for the individual power supply inputs, in

addition to an output to signal such an event on any of the

power supply inputs adds unparalleled system protection ca-

pability.

The LMV7231’s +2.2V to +5.5V power supply voltage range,

low supply current, and input/output voltage range above V+

make it ideal for a wide range of power supply monitoring ap-

plications. Operation is guaranteed over the -40°C to +125°C

temperature range. The device is available in a 24-pin LLP

package.
