BQ40Z50: Is the BTP_INT pin on BQ40Z50 open-drain output?

Dear TI Team,

I’m working on a design using the BQ40Z50-R2 fuel gauge. I have a question regarding the BTP_INT pin output type.

Is the BTP_INT pin configured as an open-drain output, or is it push-pull? I couldn’t find a clear description in the datasheet or technical reference manual.

If it is open-drain, do I need to add an external pull-up resistor?

Thank you!
