Thermal Specifications
The 82541ER device is specified for operation when the ambient temperature (T
range of 0
T
TJ (junction temperature) is calculated using the equation:
P (power consumption) is calculated by using the typical I
thermal resistances are shown in
Thermal resistances are determined empirically with test devices mounted on standard thermal test
boards. Real system designs may have different characteristics due to board thickness, arrangement
of ground planes, and proximity of other components. The case temperature measurements should
be used to assure that the 82541ER device is operating under recommended conditions.
