I have seen the VOL value specified in datasheet for MPL3115A2 for SDA lines as VOLS = 0.1VDDIO specified for Io=500uA i.e 0.33V @ Io=500uA
as Im using VDDIO 3.3V. I have pull up resistors of 10kOhm connected.
I want to analyse the variation in VOL value i.e my actual sink current 3.3/10k=0.33mA .
Is it possible to obtain the VOL values at this current. Or can it take it like Rds on of MOSFET =0.33/500uA=660Ohm
as use it to calculate the VOL @ 0.33mA as 0.33mA x 660Ohm =0.2178V Will it be correct?
