Note) Do not apply external currents or voltages to any pins not specifically mentioned.
For circuit currents, '+' denotes current flowing into the IC, and '−' denotes current flowing out of the IC.
*1: Except for the operating ambient temperature and storage temperature, all ratings are for Ta = 25°C.
*2: The voltage in the step-up voltage circuit exceeds the supply voltage.
For the allowable value of the step-up voltage, refer to "s Electrical Characteristics".
*3: For 70°C and IC alone.
