Do not apply a positive or negative voltage source to these pins, otherwise permanent damage may occur.

2

The LT8350S is specified over the –40°C to 125°C operating junction temperature range. High Junction temperatures degrade

operating lifetimes. Note that the maximum ambient temperature consistent with these specifications is determined by specific

operating conditions in conjunction with board layout, the rated package thermal impedance, and other environmental factors.

3

The LT8350S includes overtemperature protection that is intended to protect the device during momentary overload conditions.

Junction temperature will exceed 150°C when overtemperature protection is active. Continuous operation above the specified

absolute maximum operating junction temperature may impair device reliability or permanently damage the device.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These

are stress ratings only, functional operation of the product at these or any other conditions above those indicated in

the operational section of this specification is not implied. Operation beyond the maximum operating conditions for

extended periods may affect product reliability.
