Apr 5, 2020 at 7:55 | comment | added | vtolentino | Since the current flowing through the load side's diode causes a voltage drop equal to \$V_{drop} = I_{load}\cdot R_S + V_{D,fwd}\$, the uC and the sensor will draw current from the supply rail with the higher voltage. I will update my answer, in case you still want some active switching. | |
Apr 5, 2020 at 7:25 | comment | added | Alexey Kamenskiy | I think that would still cause some power going through the diode on load side due to diode internal resistance. Which is exactly what I would like to avoid as this is intended for rather precise measurements. | |
