I'm designing a protection circuit for a single cell Li-ion battery using LTC4365-1 IC. The operational voltage range of the cell is from 2.5-4.2V.
My UV(threshold) is around 2.7V and OV(threshold) is around 4.35V. Based on the equations provided in the datasheet, I've got R1=187Kohm , R2=113Kohm and R3=1330Kohm as the sense resistor values. Just want to cross-check if they are right for my application. I've done the simulation on LT-spice and posted a picture of it below.
Second, will SI9926CDY-T1-GE3 (dual N-channel MOSFET) be suitable for my design wherein Vin= 3.3-4.2V?
Finally, is it possible to attach an LED on the FAULT pin as an indicator?
