Note: The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even
for a moment. Do not exceed any of these ratings.
Exceeding the rating (s) may cause breakdown, damage or deterioration of the device, and may result in injury by
explosion or combustion.
The value of even one parameter of the absolute maximum ratings should not be exceeded under any circumstances.
The TB62214FG/FTG does not have overvoltage protection. Therefore, the device is damaged if a voltage exceeding
its rated maximum is applied.
All voltage ratings including supply voltages must always be followed. The other notes and considerations described
later should also be referred to.
