Remark
It is possible to apply a maximum of 1 W of power when the ambient temperature is 25°C or lower.
When the ambient temperature is higher than 25°C, derate based on the above chart.
It is possible to apply 0.6 W to the IC when the ambient temperature is 75°C, which is within recommended
ambient temperature conditions.
