Hi All,
I am trying to design a li-ion charger for a project. I have selected the LTC4008 charger, built and tested the circuit an everything seems fine. However in the reference design found in LTC4008 datasheet there is a schottky diode (D2) connected in parallel to the charge switch as can be seen in the attached picture. I have also tested the circuit without this diode and it still works. It is a fairly large component and I would like to not use it if I can however I can't understand what it does so I would be very gratefull if someone can explain me its purpose.
Best Regards
