BQ79616-Q1: problem with auto addressing

Part Number: BQ79616-Q1 Hi, I am having problems with auto addressing a 616 with a bq79600 bridge. The data sheets of the 600 and the 616 do not agree how this is done but I tried both methods (and hundreds others) without success. To simplify things at the moment I have a 600 followed by a single 616. Below is a software trace of the messages sent and received. The reading back of the addresses after the auto addressing sequence (the 616 data sheet version shown) fails, neither the 600 nor the 616 is responding. reading register 0x2001 from the 600 works though (bottom). bq79616.c   frm_snd(sng wri, adr 0, reg 0x0309, len 1) 0x90 0x00 0x03 0x09 0x20 0x13 0x95

 What have I missed? Regards, Hagen .

Hi Hagen, These parts are under NDA so we need to support this in private chat or email instead of E2E forum, the short answer is we provide sample code/guide and GUI after NDA is setup to reference. Can you identify and contact thecompany contact used to get the parts? Regards, Taylor

Hi Taylor, how can I send you an email? Regards, Hagen .

Hagen, Please provide your email, and I will contact you. Kindly resolve this thread afterwards. Thanks, Taylor
