Supply voltage range

Note) Do not apply external currents and voltages to any pin not specifically mentioned.

Voltage values, unless otherwise specified, are with respect to GND. GND is voltage for AGND1, AGND2, PGND1, PGND2.

AGND1 = AGND2 = PGND1 = PGND2. Vin is voltage for AVIN, PVIN1, PVIN2. AVIN = PVIN1 = PVIN2.

*1 : Please set the rising time of power input pin to the following range.

In addition, please input the voltage with the rising time which has margin enough in consideration of the variation

in external parts.

*2 : The values under the condition not exceeding the above absolute maximum ratings and the power dissipation.

μs < Tr < 1.5 ms

(Tr is the rise time from 0 V to the setup voltage of V
