| Jan 22, 2019 at 5:01 | comment | added | D.A.S. | You may want to measure short term ESR and long term ESR which have different time constants using current sense and active loads electronics.stackexchange.com/questions/376850/… It depends if you choose high or low side sensing and loading for Pch Nch options. Look at Battery Coulomb counter IC designs | |
| Jan 22, 2019 at 4:21 | comment | added | xakepp35 | @Jasen But that is at least doable, that is great | |
| Jan 22, 2019 at 4:20 | comment | added | Jasen Слава Україні | you stillneed to control the gate - you could use a resistor pull-up and another N-FET do that I guess. | |
| Jan 22, 2019 at 4:19 | comment | added | xakepp35 | @Jasen What if I add 12v rail as a power source? | |
| Jan 22, 2019 at 4:17 | comment | added | Jasen Слава Україні | a boost converter could do it. but not easier than a P-FET | |
| Jan 22, 2019 at 3:57 | comment | added | xakepp35 | @Jasen So, a P mosfet actually better fits here (as it requires gate pulled below). Thanks for remark. So you vote for it is impossible, or would require some boost converter? | |

| Jan 22, 2019 at 3:54 | comment | added | Jasen Слава Україні | you don't need to short the +5 got ground, only the bottom end or R2 needs to be connected to +5. That's going to be tricky to do with a N-channel-MOSFET because to do that you need a voltage higher than 5V for the MOSFET gate. | |
