Monitoring ambient temperature does not guarantee that TJ is within the specified temperature limits. In applications with moderate power dissipation and low PCB thermal resistance, the maximum ambient temperature can exceed the maximum limit as long as the junction temperature is within specification limits. The junction temperature, TJ, of the device is dependent on the ambient temperature, TA, the power dissipation of the device, PD, and the junction to ambient thermal resistance of the package, θJA. Maximum junction temperature is calculated from the ambient temperature and power dissipation using the formula TJ = TA + PD × θJA. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Absolute maximum ratings apply individually only, not in combination. Unless otherwise specified all other voltages are referenced to GND. ESD CAUTION |
