The characteristics of the IC are greatly influenced by the operating temperature. If the temperature exceeds the maximum
junction temperature T
dissipation is within the permissible range in order to prevent instantaneous damage resulting from heat and maintain the
reliability of the IC for long-term operation.
The following method is used to calculate the power consumption Pc (W):
The load current Io is calculated:
Calculation Example:
Refer to the above and implement proper thermal designs so that the IC will not be used under excessive power dissipation
conditions under the entire operating temperature range.
The power consumption Pc of the IC in the event of shorting (i.e. the Vo and GND pins are shorted) can be obtained from the
following equation: Pc = Vcc  (Icca + Ishort) (Ishort: short current)
