PRELIMINARY
POWER MANAGEMENT
Applications Information (Cont.)
Thermal Information
The lifetime and performance of a driver is basically de-
termined by the drive power requirements of the load,
the thermal characteristics of the driver package and its
cooling method. The driver’s junction temperature must
be kept within the rated limit at all times. The application
system has to effectively remove the heat generated in
the driver in order for proper functions and performance.
If the junction temperature reaches 150
o
C, the internal
protection circuit will be triggered to shut down the gate
driver.
As shown in the power derating table, the SC1301A/B
has a power limit of 385mW when the ambient tempera-
ture is less than 25
o
C. As the ambient temperature
reaches 85
o
C, the allowed maximum power dissipation
for the driver will be 154mW. When the ambient tem-
perature is somewhere between 25
o
C and 85
o
C, the
power dissipation for the driver should be derated ac-
cording to the table. For each degree increasing of the
ambient temperature, 3.85mW decreasing should be
applied to the driver power dissipation. Possible cooling
methods may include using big pads, natural air-cooling
by a careful layout and forced air-cooling if necessary.
