FApplication example
FOperation notes
(1)
Do not apply voltage to control logic pins (pins 4, 5, 12,
and 13) when the V
voltage of each pin should be less than V
and should be more than the ground voltage.
(2)
When changing the rotational direction of a motor, a large
current of up to a few hundred milliamperes can flow be-
tween the motor power supply (pins 11 and 14) and
MGND (pins 1 and 8). Depending on the application, this
large output current may flow back to input pins, resulting
in output oscillation or other malfunctions. Make sure that
your design does not allow a common impedance be-
tween the large current output lines and the input section.
Suppress the power supply impedance to low levels,
otherwise output oscillation may occur.

The power dissipated by the IC varies widely with the
supply voltage and the output current. Give full consider-
ation to the package power dissipation rating when set-
ting the supply voltage and the output current.
(4)
Pins 1, 3, 6, and 8 should have the lowest potential
(ground potential) in the IC.
(5)
This circuit shuts down all the driver outputs when the
chip junction temperature is increased to about 175_C
(typical). The thermal shutdown circuit is deactivated
when the temperature drops to about 20_C (typical).
(6)
These pins have characteristics negatively correlated to
temperature. Give full consideration to the temperature
effect when using the IC.
