CAUTION)
The protection functions are provided in order to improve the ability of the ICs to withstand breakdown, and they are not intended to guarantee
safety when used under conditions outside the safe operating area or rated operating conditions.
Use of the ICs under any conditions exceeding the safe operating area or above the IOmax, and especially use in overcurrent protection areas or under
conditions in which they are subject to thermal protection, may reduce their reliability and result in permanent breakdown.

*: All the specifications are defined based on the tests that Tj is almost equal to Ta (=25°C). To suppress the rise of Tj in the junction
temperature as much as possible, it tests by the pulse loading.

*1 : The VDD 5.7V output also supplies the output currents of SW 5.7V and ACC 5.7V. Therefore, the current supply capability of the VDD 5.7V output and its
other electrical characteristics are affected by the output statuses of SW 5.7V and ACC 5.7V.
*2 : SW 5V and ACC 5.7V are not subject to a load.
