Those days,we are designing a Wireless Identification and Sensing Platform.ADP5090 harvests the energy form a reader.I got to know that ADP5090 can output valtage Intermittently.But I don't know how to chose the suitable PFET for ADP5090.
general power FET is OK for this design. or you can try the ADP198 load switch.
Thanks for your help,I will try it for my application.
And if ADP5090 needs a Non-gate chip to control the power FET?
yes, it's push-pull output with around 11kohm dirver capability. for the small power FET, I think it's enough.
Thanks a lot !
Hello ,when I set the voltage term at 3v (R term1 equales 3.92M,R term2 equales 6.04M),the voltage PG at 2.4v (R pg1 equales 5M,R pg2 equales 5M),the voltage SD at 2.1v (R sd1 equales 4.53M,R sds2 equales 5.49M). But I can not catch a rising up in Pin PGOOD even the voltage at storage capacitor equales 4v?
