REV. A
CAUTIONS ON USE
(1)
When the voltage applied on the Bias terminal (pin 1) has dropped to 0.7V (Typ.) or less, the mute
function will be activated.
Under conditions of normal use, it should be set to 1.3V or above.
(2)
When the power supply voltage drops to 3.8V (Typ.) or less, the internal circuit will be OFF and, when
recovering to 4.0V (Typ.) or above, the circuit will startup again.
(3)
Thermal shutdown (TSD), bias terminal voltage drop or power supply voltage drop will activate the
mute functions for the circuits in all channels, where the output terminals will show the value of the
internal bias voltage (Vcc/2).
(4)
Setting the Standby terminal to open or 0.5V or less leads all the circuits in the channel to the standby
mode.
Under conditions of normal use, the Standby terminal should be pulled-up to 2V or above.
(5)
Setting both two Standby terminals to open or 0.5V or less allows the circuit current to be in the
standby mode.
The switched threshold voltage is approximately 1.4V.
(6)
Vcc of the pre part must be provided with the same voltage as Vcc of the power part or higher.
(7)
The source current of the pre-stage OP-amp is a constant current and the input resistance of the
next-stage driver: 10k
Ω is also internally connected as a load.
Careful consideration must be given when determining the external load resistance value of the
OP-amp.
(8)
Even though a radiating fin is connected to the GND inside of the package, it must be connected to the
external GND.
(9)
About absolute maximum ratings
Exceeding the absolute maximum ratings, such as the applied voltage or the operating temperature
range, may cause permanent device damage.
As these cases cannot be limited to the broken short
mode or the open mode, if a special mode where the absolute maximum ratings may be exceeded is
assumed, it is recommended to take mechanical safety measures such as attaching fuses.
(10) About power supply lines
As a measure against the back current regenerated by a counter electromotive force of the motor, a
capacitor to be used as a regenerated-current path can be installed between the power supply and
GND and its capacitance value should be determined after careful check that any problems, for
example, a leak capacitance of the electrolytic capacitor at low temperature, are not found in various
characteristics.
(11) About GND potential
The electric potential of the GND terminal must be kept lowest in the circuitry at any operation states.
(12) About thermal design
With consideration of the power dissipation (Pd) under conditions of actual use, a thermal design
provided with an enough margin should be done.
(13) About operations in a strong electric field
When used in a strong electric field, note that a malfunction may occur.
(14) ASO
When using this IC, the output Tr must be set not to exceed the values specified in the absolute
maximum ratings and ASO.
(15) Thermal shutdown circuit
This IC incorporates a thermal shutdown circuit (TSD circuit).
When the chip temperature reaches the
value shown below, the coil output to the motor will be set to open.
The thermal shutdown circuit is designed only to shut off the IC from a thermal runaway and not
intended to protect or guarantee the entire IC functions.
Therefore, users cannot assume that the TSD circuit once activated can be used continuously in the
subsequent operations.

(16) About earth wiring patterns
When a small signal GND and a large current GND are provided, it is recommended that the large
current GND pattern and the small signal GND pattern should be separated and grounded at a single
point of the reference point of the set in order to prevent the voltage of the small signal GND from being
affected by a voltage change caused by the resistance of the pattern wiring and the large current.
Make sure that the GND wiring patterns of the external components will not change, too.
