Hi,
I'm designing a device where I need to measure power and the INA226 is a great device for this task but I want to know if the VBUS pin is protected against reverse polarity or if there is an easy way to protect it from it like putting a high enough resistro in the VBUS pin to limit the current for any protection diode in that input.
In case of not having such a thing, I'm thinking of using a comparator in the inputs to activate a MOSFET to stop the flow of current if the polarity is reversed. I can't use a diode since it would just take too much power from the load.
Does anyone has any ideas that could help me ?
Thank you.
