THERMAL CHARACTERISTICS
PQFP Package
The Am186CC controller is specified for operation with
case temperature ranges from 0•C to +100•C for 3.3 V
± 0.3 V (commercial). Case temperature is measured
at the top center of the package as shown in Figure 14.
The various temperatures and thermal resistances can
be determined using the equations in Figure 15 with
information given in Table 8.
The total thermal resistance is q
q
and q
48
JC
, the internal thermal resistance of the assembly,
CA
, the case to ambient thermal resistance.
