LMV7231  
Hex Window Comparator with 1.5% Precision and 400mV  
Reference  
General Description  
Features  
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.  
(For VS = 3.3V ±10%, Typical unless otherwise noted)  
High accuracy voltage reference: 400 mV  
Threshold Accuracy: ±1.5% (max)  
Wide supply voltage range +2.2V to +5.5V  
Input/Output voltage range above V+  
Internal hysteresis: 6mV  
Propagation delay: 2.6 µs to 5.6 µs  
Supply Current 7.7 µA per channel  
24 lead LLP package  
Temperature range: -40°C to 125°C  
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.
