Hello Community,
I have an observation from my attempt to daisy chain multiple AEK-POW-BMS63EN devices.
I have made a battery pack which has two 14-cell Battery modules in series. One module is supposed to be connected to one AEK-POW-BMS63EN and send data over ISOSPI lines back to the AEK-ISOSPI-SPI Translator and then to the master, which is AEK-MCU-C4MLIT1.
I validated the individual slaves first, and they were working. However, when I connected the ISOH line of my first slave with the ISOL line of the second slave, it created a short circuit, and the slave IC burnt. I want to know what the correct configuration is for connecting the ISOSPI lines for a daisy chain.
I have attached my configuration in the attached photo.
Thank you
Regards,
Vipul
