Absolute Maximum Ratings (Ta=25°C)

(Note 1) When mounted on ROHM Standard board(70x70x1.6 (mm3), derate by 8.5mW/°C for Ta=25°C or more.

Thermal resistance θja = 117.6(°C/W)

Material : A FR4 grass epoxy board(3% or less of copper foil area)

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.
