Hi teams

I have a question about pin of OUT A/B.

Which pin of function do they have, open drain or push pull?

Best regards

Hi Hayashi-san,

Looking at the datasheet the OUTA and OUTB are specified to supply 200mA of current sinking and sourcing, this suggest they are push pull type outputs and not open drain.

Hi Peter-san

Thank you for your reply.
Would you tell me other the question?

My question is how much level of voltage do its OUTA/B output?
I think it can output voltage of VDD level.

Please point out any mistakes I make.

Best regards
Hayashi

Hi Hayashi-san,

I think it would be within the a Vce voltage drop of Vdd and 0V, so Vout max Vdd-Vce and Vout min 0V + Vce where Vce would be 0.3V typical.

Peter
