THERMAL SHUT-DOWN
The presence of a thermal limiting circuit offers the following advantages:
1) An overload on the output (even if it is permanent), or an above limit ambient temperature can be easily
tolerated since the Tj cannot be higher than 150
°C.
2) The heatsink can have a smaller factor of safety compared with that of a conventional circuit. There is
no possibility of device damage due to high junction temperature.
If for any reason, the junction temperature increases up to 150
°C, the thermal shut-down simply reduces
the power dissipation and the current consumption.
The maximum allowable power dissipation depends upon the size of the external heatsink (i.e. its thermal
resistance); fig. 32 shows this dissipable power as a function of ambient temperature for different thermal
resistance.
