MP2625B, SYSFB input current specification

Battery Management
1

The specification MP2625B Rev. 1.04 does not show any values for the input current of the SYSFB input.
Typically it should be zero. But for Vsys tolerance calculation depending on the voltage dividers signal resistance I need a specification of the SYSFB min./max input current within MP2625’s operating temperature range.

Do you have some numbers?

Hello lars.rinze,

looking into this and will get back to you.

Hello lars.rinze,
Our team let me know that you could expect up to around 20nA.

Thanks a lot for this information!
20 nA is a quite low value for the full operating temperature range; you seem to have good production procceses.
