SI-7300A and SI-7330A
Application Note
I
Thermal design
The procedures for the thermal design of the SI-7300A are
as follows:
(1) As shown in the right figure, the supply current I
CC1
and
the output current lo are measured at the maximum
level of the supply voltage V
CC1
. However, the motor is
in holding mode at the 2-phase excitation.
(2) From the above measurements, the internal power dis-
sipation (2 phases) of the hybrid IC can be obtained
through the following formula.
Pdiss = V
CC1

CC1
– 2Io

(R

)
Where R
L
: coil resistance of the motor per phase
Shown in the lower graphs are sample calculations of
Pdiss vs. Io.
(3) The heatsink area corresponding to the ambient tem-
perature can be obtained from the SI-7300A derating
curve shown in the lower right.
(4) Verify that the temperature of the aluminum base plate
of the hybrid IC or adjacent heatsinks is below 85
°
C
(equivalent to max. ambient temperature) when operat-
ing under actual conditions.
