LMV7231  
SNOSB45F –FEBRUARY 2010–REVISED JANUARY 2016  
LMV7231 Hex Window Comparator With 1.5% Precision and 400-mV Reference  
1 Features  
3 Description  
The LMV7231 device is a 1.5% accurate Hex  
Window Comparator which can be used to monitor  
power supply voltages or any other analog output,  
such as an analog temperature sensor or current-  
sense amplifier. The device uses an internal 400-mV  
reference for the comparator trip value. The  
comparator set points can be set through external  
resistor dividers. The LMV7231 has 6 outputs (CO1  
to CO6) that signal an undervoltage or overvoltage  
event for each power supply input. An output (AO) is  
also provided to signal when any of the power supply  
inputs have an overvoltage or undervoltage event.  
This ability to signal an undervoltage or overvoltage  
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.

Undervoltage and Overvoltage Detection  
High Accuracy Voltage Reference: 400 mV  
Threshold Accuracy: ±1.5% (Maximum)  
Wide Supply Voltage Range 2.2 V to 5.5 V  
Input and Output Voltage Range Above V+  
Internal Hysteresis: 6 mV  
Propagation Delay: 2.6 µs to 5.6 µs  
Supply Current 7.7 µA Per Channel  
24-Lead WQFN Package  
Temperature Range: –40°C to +125°C  
2 Applications  
The 2.2-V to 5.5-V power supply voltage range, low  
supply current, and input or output voltage range  
above V+ make the LMV7231 ideal for a wide range  
of power supply monitoring applications. Operation is  
ensured over the –40°C to +125°C temperature  
range. The device is available in a 24-pin WQFN  
package.
