1. The thermal limit is set above the maximum thermal ratings. It is not recommended to operate the device at temperatures greater than the

maximum ratings for extended periods of time.

Note:

Absolute maximum ratings are those values beyond which damage to the device may occur. Functional

operation under these conditions is not implied. Exposure to absolute maximum rating conditions may affect

device reliability. All values are referred to GND.

1. The maximum allowable power dissipation is a function of the maximum junction temperature TJ-OP = 125 °C, the junction-to-ambient

thermal resistance RthJA, and the ambient temperature TA and can be estimated by: PD(MAX) = (125 °C - TA) /RthJA. Exceeding the

maximum allowable power dissipation produces overheating that may cause thermal shutdown.
