Recently we received three customer claims, and we noticed that the 6584 powerstage was not working propery due to loss of 12c communication.And we further noticed that the loss of l2c communication happened right after a chip SW RESET(with Mode CTRL RegisterThe l2C address is changed from 0xC2 to 0xC0. And this behavior is sporadic.
In our schematic, we use a 1K pull-down register, so the address is supposed to be 0xC2.
