I am trying to understand how to use this configuration of the LTC2992 power measure IC and the only part I am confused with so far is the two transistors which I have circled.
What I know so far about this part is the ORGND will change between being rather ground or a maximum of -95V. The GPIO pins are set to input they are both open drain. I don't understand the point of these transistors even after going through the datasheet unless I have missed something. I only theory is that they are acting as diodes so far. Heres a link to the datasheet
The IC itself is meant to be able to sense the power across the sense resistor and then send this data to a master.
