FThermal derating curves
As the allowed power dissipation of the BA3430F /
BA3430FS is small (BA3430F = 550mW, BA3430FS =
800mW), high temperature or high current may cause
the allowed power dissipation to be exceeded. Fig. 8
shows the internal power dissipation vs. supply voltage
(Pd vs. V
), and Fig. 9 shows the allowed power dissipa-
CC
tion vs. ambient temperature (Pd
vs. Ta). Allowed

can be obtained from these curves, and the result is
shown in Fig. 10. Refer to Fig. 10 to set the supply voltage
when designing the application.
