Please refer to maximum current voltage of the electrical characteristic item. (Note 2) Mounted on 70mm x 70mm x 1.6mm glass epoxy board. Reduce 4.5mW per 1C above 25C. Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
