Note). For the actual usage, please refer to the PD-Ta characteristics diagram in the package specification, supply
voltage, load and ambient temperature conditions to ensure that there is enough margin follow the power and
the thermal design does not exceed the allowable value.
Although this has limited built-in ESD protection circuit, but permanent damage may occur on it.
Therefore, proper ESD precautions are recommended to avoid electrostatic damage to the MOS gates
