BMP388 VOL, VIL, drive current

[BillyB0B]

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.

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.
