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.

12. Power saving circuit
This IC goes into a power saving state in which current drain is reduced when set to the stop state. This power saving
state is implemented by cutting the bias current to most of the circuits in the IC. The 5V regulator output, however, is
still output when the IC is in the power saving state.
13. Error amplifier system components
The external components for the error amplifier block must be located as close as possible to the IC to minimize the
influence of noise. These components must also be located as far from the motor as possible.
14. Forward/reverse switching
In principle, forward/reverse switching must be performed with the motor in the stopped state.
This IC does provide circuit workarounds for handling the through currents that occur during switching if the direction
is switched while the motor is turning. However, care is required with respect to lifting of the motor supply voltage
during this switching, since the motor current will return to the power supply during brief instants. If this becomes a
problem, the size of the capacitor connected between the power supply line and ground must be increased.
If the motor current after switching exceeds the current limit value, the PWM drive side output will be turned off.
However, the opposite side output will go to the short-circuit braking state and a current determined by the motor
induced voltage and the coil resistance. This current must be held under the current rating of the output transistors used.
(This aspect requires more care the faster the motor speed at which forward/reverse switching occurs.)
15. Brake switching
Either free running or short-circuit braking can be selected with the BRSEL pin.
The short-circuit braking mode adopts a form in which all phases of the PWM drive side output transistors are turned
on (all phases of the reverse side transistors are turned off). Care is required, since the current limiter function does not
operate during braking. During braking, the output circuits go to a shorted state with 100% duty. The current that flows
in the output transistors during braking is determined by the motor induced voltage and the coil resistance. This current
must be held under the current rating of the output transistors used. (This aspect requires more care the faster the motor
speed at which braking occurs.)
16. NC pins
Since the NC pins are electrically open, they can be used for intermediate wiring connections without problem.
