4.5µA Li-Ion Battery Protection Circuit

Hi Team

I tried to simulate the circuit given in your design note "https://www.analog.com/en/technical-articles/battery-protection-circuit.html"

According to the designer, the cut off voltage is 3V but the circuit is not going to cut off when the i/p is below 3V also.

Please see the attached simulation result. Could you please help me how to solve this issue.

Regards

Hari
