Dear Specialists,

My customer'd like to know where to connect SYNC_OK pin when unused.

SYNC_OK pin is Open Drain, generally it should be open, is it correct.

I appreciate your great help in advance.

Best regards,

Shinichi

Hi Shinichi,

If the SYNC function is not used then SYNC and SYNC_OK should both be connected to GNDP so that SYNC=SYNC_OK=GNDP.

Hi Steve,

Thank you for your reply.

I understand SYNC and SYNC_OK should be connected to GNDP when SYNC is not used.

I'll share this information with the customer.

I appreciate your great help and cooperation.

Best regards,

Shinichi
