CAUTIONS ON USE
(1)
Setting the voltage on the Mute terminal to open or 0.5V or less will activate a mute function for the
output current.
Under conditions of normal use, the Mute terminal should be pulled-up to 1.5V or
above.
(2)
When the voltage applied on the Bias terminal (pin 20) has dropped to 0.7V (Typ.) or less, the mute
function will be activated.
Under conditions of normal use, it should be set to 1.1V or above.
(3)
When the power supply voltage drops to 3.8V (Typ.) or less, the mute function will be activated and,
when recovering to 4.0V (Typ.) or above, the circuit will startup again.
(4)
Thermal shutdown (TSD) or power supply voltage drop will activate the mute functions on all drivers,
while mute ON or bias terminal voltage drop will on the BTL drivers except loading drivers.
The
pre-stage OP-amps cannot be muted in any cases described above.
While muting, the output
terminals of the BTL driver are set to the value of the internal bias voltage ((VCC-0.7)/2V).

(6)
Even though a radiating fin is connected to the GND inside of the package, it must be connected to the
external GND.
(7)
Basically, applying a voltage below the IC sub-potential to any terminals must be avoided.
Due to a
counter electromotive force of the load, if the output on each driver has dropped to the IC sub-potential
(GND) or less, an operation margin must be considered and examined.
(8)
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.
(9)
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.
(10) About GND potential
The electric potential of the GND terminal must be kept lowest in the circuitry at any operation states.
(11) 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.
(12) About operations in a strong electric field
When used in a strong electric field, note that a malfunction may occur.
(13) ASO
When using this IC, the output Tr must be set not to exceed the values specified in the absolute
maximum ratings and ASO.
(14) Thermal shutdown circuit (Thermal shutdown: TSD)
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.
