Caution: Operating the IC over the absolute maximum ratings may damage the IC. In addition, it is impossible to

predict all destructive situations such as short-circuit modes, open circuit modes, etc. Therefore, it is important to

consider circuit protection measures, like adding a fuse, in case the IC is operated in a special mode exceeding the

absolute maximum ratings.
