(Note1)

Power dissipation deleting is 13mW/°C, when it’s used in over 25°C

(ROHM’s standard one layer board has been mounted.)

The power dissipation of the IC has to be less than the one of the package.

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.
