Thermal design should allow operation within the following conditions. Note that the temperatures listed are the allowed
temperature limits, and thermal design should allow sufficient margin from the limits.
1. Ambient temperature Ta can be no higher than 85 ℃ .
2. Chip junction temperature (Tj) can be no higher than 150 ℃ .
Chip junction temperature can be determined as follows:
Calculation based on ambient temperature (Ta)
Tj=Ta+ θ j-a × W

Most of the heat loss that occurs in the BD00HA3WEFJ is generated from the output Pch FET. Power loss is determined by
the total V CC -V O voltage and output current. Be sure to confirm the system input and output voltage and the output current
conditions in relation to the heat dissipation characteristics of the V CC and V O in the design. Bearing in mind that heat
dissipation may vary substantially depending on the substrate employed (due to the power package incorporated in the
BD00HA3WEFJ make certain to factor conditions such as substrate size into the thermal design.
Power consumption [W] = Input voltage (V CC ) - Output voltage (V O ) × I O (Ave)
Example) Where V CC =5.0V, V O =3.3V, I O (Ave) = 0.1A,
Power consumption [W] = 5.0V - 3.3V × 0.1A
=0.17[W]
