Hello,
I have designed a Window comparator using LTC1040 for undervoltage lock out(LTSPICE). The battery supply should be cut of to hardware if the battery voltage falls out of range.
My operational criteria is
Battery supply is 39.2 V.
Upper limit Voltage 39.1V
Lower Limit Voltage 23.8V.
The comparator should give be High only in between the Limits.
Comparator is working good and the output at Nmos is as expected(39,2V).Although I have checked with the resistor value the output at the Vout is touching only to 36V only while it has to be 39.2
I could not understand what the problem is.
Please help me out.
Thank you.
