... BH1780GLI ●Cautions on use 1) Absolute Maximum Ratings An excess in the absolute maximum ratings, such as supply voltage ( Vmax ), temperature range of operating conditions ( Topr ), etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures including the use of fuses, etc ...
