SANYO Semiconductor Co.,Ltd. assumes no responsibility for equipment failures that result from using
products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor Co.,Ltd.
products described or contained herein.
SANYO Semiconductor Co.,Ltd. strives to supply high-quality high-reliability products, however, any and all
semiconductor products fail or malfunction with some probability. It is possible that these probabilistic failures or
malfunction could give rise to accidents or events that could endanger human lives, trouble that could give rise
to smoke or fire, or accidents that could cause damage to other property. When designing equipment, adopt
safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not
limited to protective circuits and error prevention circuits for safe design, redundant design, and structural
design.

11. Power supply stabilization
Because this IC provides a high output current and uses a switching drive technique, power supply line fluctuations
can occur easily. Therefore, a capacitor of sufficient capacitance (several ten
F or higher) must be connected
between the VCC pin and ground to assure stable operation. The ground connection of this capacitor must be
connected to the GND2 pin, which is the power block ground, at a point as close as possible to the IC. If, due to
problems associated with the heat sink, the (electrolytic) capacitor cannot be connected near the this pin, a ceramic
capacitor of about 0.1
F must be connected near the pin.
Since the likelihood of power line fluctuation increases if diodes are inserted in the power supply lines to prevent
destruction of the IC if power is connected with reverse polarity, a larger capacitance will be required.
12. VREG stabilization
A capacitor (about 0.1
F) must be connected to the VREG pin (the 5V regulator output), which functions as the
control circuit power supply, for stabilization. The ground side of this capacitor must be connected to the GND1 pin
with a lead that is as short as possible.
13. Integrating amplifier related component values
The external components used in the integrating amplifier must be located as close as possible to the IC to
minimize the circuit’s susceptibility to noise. These components must be located as far as possible from the motor.
