increased to reduce the HCPL-3150 power dissipation.

For Qg = 500 nC, from Figure 27, a value of E
gives a Rg = 41 Ω.
Thermal Model (HCPL-3150)
The steady state thermal model for the HCPL-3150 is
shown in Figure 28a. The thermal resistance values given
in this model can be used to calculate the tempera tures
at each node for a given operating condition. As shown
by the model, all heat generated flows through T
raises the case temperature T
T
is, therefore, determined by the designer. The value of
