STPMIC25 latching

Hello,

I'm in the process of moving from MP1 to MP2 on my device. The latter, used STPMIC1 that suffered the startup problem as described in AN5861 and I had to go thru a re-design to include the latching circuit on my PCBA.

Can anybody confirm that this issue is gone for STPMIC25 that I will use for MP2?

Thanks in advance,
Daniel

Hello Daniel,

 

yes, STPMIC25 use different startup method and no issue if the input voltage is dropping fast.
