Note 1: The maximum power dissipation is a function of TJMAX, JA and ambient temperature T
A
. The maximum
allowable power dissipation at an ambient temperature is P
D = (TJMAX - TA)JA. If this dissipation is
exceeded, the die temperature will rise above 150C and the device will go into thermal shutdown.
