A voltage rising rate of 50 mV/ms or
less is recommended.
Sudden change in supply voltage during operation may initiate a power-on sequence.
To change supply voltage during operation, it is recommended to smoothly raise the voltage to avoid rapid
fluctuations in the supply voltage.
Note:
Note: Set RST pin to “L” level when turning on the device, at least the described above duration after the
supply voltage reaches Vcc is necessary before turning the RST to “H” level.
