Current Monitoring Resistor
The current monitor works by creating a proportional current to the one flowing through the eFuse.
According to the datasheet, the formula for determining the resistance of a particular load current is…

$ R_{IMON} (\Omega) = \frac{V_{IMON}(\mu V)}{I_{LOAD} (A) * G_{IMON}(\mu A/A)} = \frac{V_{IMON}(V)}{I_{LOAD} (A) * G_{IMON}(\mu A/A)*10^6}$ |

Our ADC can read a maximum value of 3.3 V (most likely, need to confirm), so V_IMON = 3.3 V.
The maximum ILOAD of the eFuse is 18 A. Although most, if not all, of our outputs will not utilize that full quantity, we will
On page 24 of the TPS25983 datasheet, the following formula is also shown in terms of
