(Note4) Derate by 7.00mW/°C when operating above Ta=25°C (when mounted in ROHM’s standard board (BU91600FV-M)).
Derate by 6.40mW/°C when operating above Ta=25°C (when mounted in ROHM’s standard board (BU91600FUV-M))
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.
