LMV7231 Hex Window Comparator with 1.5% Precision and 400mV Reference
December 16, 2010
LMV7231 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 capability. The LMV7231's +2.2V to +5.5V power supply voltage range, low supply current, and input/output volta
