    BMP388 VOL, VIL, drive current

    Hello,

    I would like to use the BMP388 on a bus that has a fairly low valued pull-up resistor (<1 kOhm). In order to guarantee compatibility with your device, can you please provide the following information?

    • VIL - Input voltage low
    • VOL - Output low voltage (@ 4.5mA)
    • Max drive current

    Thank you.

    Re: BMP388 VOL, VIL, drive current

    VIL <= 0.25 VDDIO

    VOL <= 0.2 VDDIO (@3mA)

    Sorry,  didn't find drive current information.

    Hello,

    Thank you for the quick response. I don't need to know exact drive current requriements, but can you please confirm that it will be safe to use a pull up that needs to sink ~4.5 mA? Maybe say 5 mA to be safe.

    Thanks!

    It should be fine even we only test with 3mA now.
