- Note 1: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the product or equipment. Note 2: These protection functions are intended to avoid some output short circuits or other abnormal conditions temporarily. These protect functions do not warrant to prevent the IC from being damaged. - In case of the product would be operated with exceeded guaranteed operating ranges, these protection features may not operate and some output short circuits may result in the IC being damaged. 1
