HEAT SINK DIMENSIONING:
In order to avoid the thermal protection intervention, that is placed approximatively at Tj = 150°C, it is important
the dimensioning of the Heat Sinker RTh (°C/W).
The parameters that influence the dimensioning are:
– Maximum dissipated power for the device (Pdmax)
– Max thermal resistance Junction to case (RTh j-c)
– Max. ambient temperature Tamb max
– Quiescent current Iq (mA)
Example:
VCC = 22V, Rload = 8ohm, RTh j-c = 5 °C/W , Tamb max = 50°C
Pdmax = (N° channels)
Pdmax = 2 ( 3.0 ) + 0.5 = 6.5 W
(Heat Sinker)
In figure 21 is shown the Power derating curve for the device.
