Please let me know your advice the relationship and SYS and BAT of ADP5091.
The datasheet Rev.A P.16 " FIgure 41 Fast Cold Start-Up sequence" describes that
the voltage of BAT and SYS become the same value and these voltage are increased together.
( Please refer to attachment's red circle )
Accutually, the voltage of BAT is lower than that of SYS as "Figure 21 Startup with Empty 100 μF Capacitor."
Could you teach me why the voltage of BAT and SYS at this timing are differed ?
This is appeared at BAT=1.5V, SYS= about 2.2~ 2.3V in our test result.
We thought that the voltage difference is large unlike figure 21.
So, please let me know your advice if there is any problem when the difference is large.
