Absolute maximum ratings are limits beyond which damage to the device may occur. 2. The maximum allowable power dissipation is a function of maximum function temperature, TJ(max), the junction to ambient thermal resistance, RθJA, and the ambient temperature. The maximum allowable, power dissipation at any ambient temperature is calculated using: PD(MAX)=[TJ(max)-TA]/RθJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature. All limits at temperature extremes are guaranteed via correlation using standard statistical methods |
