THERMAL CHARACTERISTICS

The AU5790 provides protection from thermal overload. When the

IC junction temperature reaches the threshold (≈155 °C), the

AU5790 will disable the transmitter drivers, reducing power

dissipation to protect the device. The transmit function will become

available again after the junction temperature drops. The thermal

shutdown hysteresis is about 5 °C.

where: T is junction temperature (°C);

T is ambient temperature (°C);

P is dissipated power (W);

is thermal resistance (°C/W).

Thermal Resistance

Thermal resistance is the ability of a packaged IC to dissipate heat

to its environment. In semiconductor applications, it is highly

dependant on the IC package, PCBs, and airflow. Thermal

resistance also varies slightly with input power, the difference

between ambient and junction temperatures, and soldering material.

In order to avoid this transmit function shutdown, care must be taken

to not overheat the IC during application. The relationships between

junction temperature, ambient temperature, dissipated power, and

thermal resistance can be expressed as:

Figures 5 and 6 show the thermal resistance as the function of the

IC package and the PCB configuration, assuming no airflow.
