Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality

should not be assumed, damage may occur and reliability may be affected.

1. The maximum functional operating temperature range can be limited by the IC thermal shutdown: P_TJ_OFF.

RECOMMENDED OPERATING CONDITIONS

Operating ranges define the limits for functional

operation and parametric characteristics of the device. Note

that the functionality outside the operating ranges described

in this section is not warranted. Operating outside the

recommended operating ranges for extended periods of time

may lead to a not functional device or affect device

reliability. A mission profile is a substantial part of the

operation conditions; hence the Customer must contact

onsemi in order to mutually agree in writing on the allowed

missions profile(s) in the application.

Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond

the Recommended Operating Ranges limits may affect device reliability.

2. The parametric characteristics of the circuit are not guaranteed outside the parametric operating junction temperature range.

3. A mission profile describes the application specific conditions such as, but not limited to, the cumulative operating conditions over life time,

the system power dissipation, the system’s environmental conditions, the thermal design of the customer’s system, the modes, in which the

device is operated by the customer, etc. No more than 100 cumulated hours in life time above P_TJ.
