For answering that, you need to know about voltage drops of mosfets, how to measure 24V with a 24bit ADC(uC works on low voltages). You should give more detail if you have an opinion. | |

| Aug 22, 2021 at 9:44 | comment | added | tlfong01 | I am confused. I thought a 4-digit DVM or a 24-bit ADC's differential channel across the load (SMA wire) of course measures the voltage. The current sensing part is nevertheless BTN7971B's main trick, though not your focus or objective. | |
| Aug 22, 2021 at 9:04 | comment | added | Berker Işık | thanks, but this is not what i need. I think you gave an example of current sense, but i mean excluding voltage drop of mosfet's RDS and accurately measuring the voltage which part of only wire. | |
