Application Note
■ Determining the output
■ Power down mode
The SI-7300A can be operated in power down mode. The
current IO (motor coil current)
The output current, lo is fixed by the following circuit ele-
ments:
circuit is shown below. When transistor Tr is switched on,
the reference voltage drops and the output current can be
decreased.
RS
:
Current detection resistor
VCC2 : Supply voltage
RX Variable current resistor

:
Rx
SI-7300A
To operate a motor at maximum current level, set Rx =
infinity (open). Based on the specifications of SI-7300A, its
output current lo can be seen as:
Tr
lo (rms value): 535 to 625 mA
To compute lo when different values are used for Rs and
VCC2, use the approximation formula below. The maximum
ripple value IOH of the output current waveform can be
computed as follows:

Application Note
■ 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 ICC1 and
the output current lo are measured at the maximum
level of the supply voltage VCC1. 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.
Method for measuring current SI-7300A
Pdiss = VCC1 • ICC1 – 2Io2(RL + RS)

perature can be obtained from the SI-7300A derating
curve shown in the lower right.

of the hybrid IC or adjacent heatsinks is below 85°C
(equivalent to max. ambient temperature) when operat-
ing under actual conditions.

Handling Precautions
(Note: The SI-7502 is applicable for item (2) only.)
For details, refer to the relevant product specifications.
(1) Tightening torque:
The torque to be applied in tightening screws when mounting the IC on a
heatsink should be below 49N•m.
(2) Solvent:
Do not use the following solvents:
Substances that
dissolve the package
Chlorine-based solvents
: Trichloroethylene,
Trichloroethane, etc.
Aromatic hydrogen compounds: Benzene, Toluene,
Xylene, etc.
Ketone and Acetone group solvents
Substances that
Gasoline, Benzine and Kerosene
weaken the package
(3) Silicone grease:
The silicone grease to be used between the aluminum base plate of the hybrid
IC and the heatsink should be any of the following:
• G-746
SHINETSU CHEMICAL INDUSTRIES CO., LTD.
• YG6260 TOSHIBA SILICONE CO., LTD.
• SC102
DOW CORNING TORAY SILICONE CO., LTD.
Please pay sufficient attention in selecting silicone grease since oil in some
grease may penetrate the product, which will result in an extremely short
product life.
Others
• Resistance against radiation
Resistance against radiation was not considered in the development of these ICs
because it is assumed that they will be used in ordinary environment.
