Dear Experts,

I would like to know why I should not use DSG_PDSG_OFF(), CHG_PCHG_OFF() or FET_CONTROL() when we have DDSG and DCHG pins configured as DDSG and DCHG functions?

We actually tried all of them and they coexist fine (DDSG/DCHG with the above mentioned commands).

Regards,

Andras

Hello Andras,

The following E2E thread has an explanation and details as to why this is not recommended:

Hi Luis,

Thanks, I went through the thread. So as I understood if we do not use DDSG/DCHG pins for decision making only for diagnostic read what we can do is to mask these readings of these pins for 1-2 sec after we send for example the DSG_PDSG_OFF() command. Am I correct?

Thanks,

Andras

Hello Andras,

I think that should be okay if you are using the DDSG/DCHG pins just for diagnostic purposes. You can mask the readings for 1-2 seconds after sending DSG_PDSG_OFF().
