For INA226 may I use resistive divider for more voltage? Or can you also include INA 238 for your work? #100

I need to use this INA 2xx power sensors on a project with ESP32. But I have a bus voltage more than 36V (which is the max limit of INA226), there is a INA238 for 85 V which is is enough for my project.

But the thing is there is literally no code source (library) on the web for ina238 but there are lots of libraries for INA226. So I am planning to use a basic voltage division (like 1 to 3) with resistors to have a bus voltage less than the max limit of INA226 and then multiply it by three in the software. Is this a logical solution for this problem? It should be basic and simple as that right just I will divide my real Vbus and feed it like a fake Vbus to the sensor, all other connections and logic should be the same.

Or can you also include INA 238 for your work?

Resistive divider works fine. I use it with 226.

I think there might be confusion about the low side or high side connection. How do you implement it exactly?
