FOperation notes
(1)
Do not apply voltage to control logic pins when the V
voltage is not applied to the IC. The voltage of each pin
should be less than V
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 and the PGND pin. De-
pending 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 between the large current
output lines and the input section. Suppress the power
supply impedance to low levels, otherwise output oscilla-
tion may occur.

(3)
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)
The GND and SUB pins 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.
