Thermal Model
(Discussion applies to HCPL-3180)
The steady state thermal model for the HCPL-3180 is
shown in Figure 27. The thermal resistance values given
in this model can be used to calculate the temperatures
at each node for a given operating condition. As shown
by the model, all heat generated flows through q
raises the case temperature TC accordingly. The value of
q
is, therefore, determined by the designer. The value of
