Notes for use

1) Absolute maximum ratings

Devices may be destroyed when supply voltage or operating temperature exceeds the absolute maximum rating.

Because the cause of this damage cannot be identified as, for example, a short circuit or an open circuit, it is important

to consider circuit protection measures – such as adding fuses – if any value in excess of absolute maximum ratings is

to be implemented.

2) Connecting the power supply connector backward

Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when

connecting the power supply lines, such as adding an external direction diode.
