Monitoring 3 voltages with MAX16042

Question

Hello, 
 I would like to use MAX16042 for monitoring 3 voltages and generating an alarm if any of the voltages is under a threshold. 
 The voltages I have to monitor are 5V, 12V y 24V. 
 I will configure the thresholds for each voltage, but I have a doubt about the Vcc voltage. Which one should I use? The highest one, 24V? 
 Thanks!!!

Hi isingla, 
 Vcc operating voltage range is 2.2V to 28V. I would suggest using a lower voltage to avoid reaching the abs max value of 30V just in case a voltage spike happens.)
