for the curve drawn in Figure 10-1, using the minimum and maximum values of ambient
temperature for different packages and substituting J C for J A (assuming good thermal
management). Table 10-2 provides the maximum power dissipation and average junction
temperature assuming that no thermal management is applied (i.e., still air).
MOTOROLA
Table 10-1 summarizes maximum power dissipation and average junction temperature
Figure 10-1. MC68000 Power Dissipation (P D ) vs Ambient Temperature (T A )
Since the power dissipation curve shown in Figure 10-1 is
negatively sloped, power dissipation declines as ambient
temperature increases.
dissipation occurs at the lowest rated ambient temperature, but
the highest average junction temperature occurs at the
maximum ambient temperature where power dissipation is
lowest .
