THERMAL SHUT-DOWN
The presence of a thermallimiting circuit offers the followingadvantages:
1) Anoverloadon theoutput(even if itis permanent),oran abovelimitambienttemperaturecanbeeasily
tolerated since the Tj cannot be higher than 150
°
C.
2) The heatsinkcan havea smallerfactor of safety comparedwith that of a conventionalcircuit. There is
no possibility of device damage due to high junction temperature.
Ifforanyreason,thejunctiontemperatureincreasesupto150
°
C,thethermalshut-downsimplyreduces
the power dissipationand the current consumption.
The maximum allowable power dissipationdependsupon the size of the externalheatsink(i.e. its thermal
resistance);fig. 32 shows thisdissipable power as a functionof ambient temperaturefor differentthermal
resistance.
