Power dissipation (total loss) indicates the power that can be consumed by IC at Ta=25℃(normal temperature).IC is heated
when it consumed power, and the temperature of IC ship becomes higher than ambient temperature. The temperature that
can be accepted by IC chip depends on circuit configuration, manufacturing process, and consumable power is limited.
Power dissipation is determined by the temperature allowed in IC chip (maximum junction temperature) and thermal
resistance of package (heat dissipation capability). The maximum junction temperature is typically equal to the maximum
value in the storage temperature range. Heat generated by consumed power of IC radiates from the mold resin or lead frame
of the package. The parameter which indicates this heat dissipation capability (hardness of heat release) is called thermal
resistance, represented by the symbol θj-a[℃/W]. The temperature of IC inside the package can be estimated by this
thermal resistance. Fig.319 (a) shows the model of thermal resistance of the package. Thermal resistance θja, ambient
temperature Ta, junction temperature Tj, and power dissipation Pd can be calculated by the equation below:
Derating curve in Fig.319 (b) indicates power that can be consumed by IC with reference to ambient temperature. Power that
can be consumed by IC with reference to ambient temperature. Power that can be consumed by IC begins to attenuate at
certain ambient temperature. This gradient is determined by thermal resistance θja. Thermal resistance θja depends on chip
size, power consumption, package, ambient temperature, package condition, wind velocity, etc even when the same of
package is used. Thermal reduction curve indicates a reference value measured at a specified condition. Fig.320(c), ~, (f)
show a derating curve for an example of BA4558, BA4558R, BA4560, BA4560R, BA4564R, BA4580R, BA4584, BA4584R,
BA8522R, BA15218, BA14741, BA15532, BA4510, BA2115.
When using the unit above Ta=25[℃], subtract the value above per degree[℃]. Permissible dissipation is the value.
