This rating is the maximum rating and device operating at this range is not guaranteeable as it is higher than ourstated recommended operating range. When subjected under the absolute maximum rating for a long time, the reliability ofthe product may be affected.*1: V IN = VIN.The values under the condition not exceeding the above absolute maximum ratings and the power dissipation.*2: Except for the power dissipation, operating ambient temperature, and storage temperature, all ratings are for Ta =25C.POWER DISSIPATION RATINGPACKAGE JAPD (Ta=25 C)PD (Ta=85 C)16 pin Plastic Shrink Small Outline Package (SSOP Type)171.8 C /W0.582 W0.233 WNote)For the actual usage, please refer to the P D -Ta characteristics diagram in the package specification, supply voltage, loadand ambient temperature conditions to ensure that there is enough margin follow the power and the thermal design doesnot exceed the allowable value.CAUTIONAlthough this LSI has built-in ESD protection circuit, it may still sustain permanent damage if not handledproperly. Therefore, proper ESD precautions are recommended to avoid electrostatic damage to the MOSgates.Page 4 of 21
