(Note1) Derate by 9.3mW/°C when operating above Ta=25°C (when mounted in ROHM’s standard board).

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.
