Note) Do not apply external currents or voltages to any pins not specifically mentioned expect for the power supply and GND pins.
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 T
a

25°C.
*2: The voltage in a step-up voltage circuit exceeds a supply voltage. Refer to "s Electrical Characteristics" for an allowable
value of a step-up voltage.
*3: Use within 1 000 mA in each channel 1 and channel 2.
