Hi All,
For monitoring the negative power supply voltage can I use LM193AD in the single supply mode (V+ =GND, V- =-3.3V) when i am using reference voltage input with respect to the V- of the LM193AD.

some more information.
I have tried above condition in the bread board i am facing some problem in the output of the comparator even though all inputs are fine. When I am simulating the under voltage and over voltage condtion output sate is not changing.
.
Shobhit,
Yes, 0V & -3.3V is possible.
Input common mode range will be -2V to -3.3V (VCC-2V to GND for LM193 point of view))
VOL will be near -3.3V, VOH will be whatever voltage is used for pull up resistor.
