Dying Gasp + Hotswap Feature Implementation using LTC3351

Category: Hardware
Product Number: LTC3351

Hi ADI Team,

1) Please verify my calculation, How we should decide Boost Peak Current, Please explain effect of this value on calculation because I have noticed if I will take this lower backup time is coming zero? Please confirm if I have taken correct value for my calculation?

2) If my desired hot swap current limit is 1.5 time the charger input current limit, then what should be my equivalent connection for below shown reference circuit(DC2464A - B), what is significance of R1,R2,R3,R8,D6,D7, why these 1 Ohm resistor are being used? 

Thanks.
