Hi to all, I have stumble upon this forum by Google and I have find some helpful threads close to my problem but still don't know how to solve it.
I know in theory how MOSFET works but have some problem with practice
I need to build MOSFET comparator that will switch between two different sources. Source 1. is between 0-35V and Source 2. is battery pack of 8.4V. So I need to build automatically switch that will connect LOAD to battery(Source 2) when Source 1 is under 9V, when it comes over 9V the battery is switch OFF.
So, my problem is that I don't know which MOSFET to use and have to menage this above. The maximum current will be 500mA from Source 1 and from battery the LOAD will take ~1.5A.
I will appreciate you help, and excuse me if there is similar thread, in that case I will bi grateful for showing it to me.
