I am making mini ups circuit as a project and in the project there is a part with variable resistor of 10k and transistor BC548. what I don't understand is that in the description it says that variable resistor and transistor acts as voltage comparator. i really don't know what that means. plz help me out!!

In my opinion use a single ups . If you use 8 ups it lost lot of current as losses .and a lot of places.
Calculate the full Load with the help of an electrical experts and take decision.

I have been using this IC for years and never have had such problems.
Depending on what is connected to I/Os I always use small serial resistors (10Ohm), 4.7k-10k pull-ups and 5.1V zener diodes between pins and GND.
As mentioned above decoupling caps are a must...

Yeah; I certainly agree with your point there. My point is only that most people on this forum are likely to be grown-ups, if they decided against working through the question - it is their own choice. I also feel that people have been very trigger happy with the homework assumption. Particularly, the question in this thread does not strike me as a

This circuit works as a comparator. Consider the branch with Vinp. If Vinp increases, then the current through the PMOS differential pair at that end decreases. Hence, the Vds drop on its active NMOS load decreases. For a moment consider that load to be a resistor because of the rds being modeled as a resistor. When the current is decreasing, then,

Placing diode in series with + terminal will lower supply voltage for 0.7V. This can be the reason that ups is indicating low battery. The first idea that came to my mind is to use two relays.
Relay A changes polarity if needed and relay B delays switch on until polarity is changed.

The "N" part is significantly slower and has higher capacitance than the "NF" part. That difference may or may not cause trouble in your ups circuit.
Did you replace the MOSFET because it was damaged? Maybe the circuit has another malfunction that killed the MOSFET.

hi, I am doing a project in which it is intended to design a backup power unit suitable for maintaining power for a small motor. If line power is loss it switches to battery powered inverter within less than 0.1 sec. The inverter output must be fully synchrionised to the line, so that there is limited inrush current when the switching takes place.[

ups is not constructed in a way to handle long time load . Transformators are not choosen to work in continuos mode operation. Then switching MOsFET's hs to be put onto radiators. better will be increase number of MOSFET's connected in parallel if ups is t work longer than expected.
Then it comes to charge current you have to adjust to get batt
