FOperation notes
(1)
checked; however, use of the products with applied volt-
ages, operating temperatures, or other parameters that
exceed the absolute maximum rating given may result in
the damage of the IC and the product it is used in. If the
IC is damaged, the short mode and open modes cannot
be specified, so if the IC is to be used in applications
where parameters may exceed the absolute maximum
ratings, then be sure to incorporate fuses, or other physi-
cal safety measures.
(2)
The potential for pin 1 must be kept lower than the poten-
tials of the other pins regardless of the circumstances.

electrical characteristics.
(4)
Depending on the ambient conditions, environment, or
motor characteristics, the back-rush voltage may fluctu-
ate. Be sure to confirm that the back-rush voltage will not
adversely affect the operation of the IC.
(5)
Large currents are carried by the motor power supply and
motor ground for these ICs.
Therefore, the layout of the pattern of the PC board and
the constants of certain parameters for external compo-
nents, such as the capacitor between the power supply
and ground, may cause this large output current to flow
back to the input pins, resulting in output oscillation or
other malfunctions. To prevent this, make sure that the
PC board layout and external circuit constants cause no
problems with the characteristics of these ICs.
(6)
The power dissipation will fluctuate depending on the
mounting conditions of the IC and the ambient environ-
ment. Make sure to carefully check the thermal design of
the application where these ICs will be used.

(7)
The power consumption by the IC varies widely with the
power supply voltage and the output current. Give full
consideration to the power dissipation rating and the
thermal resistance data and transient thermal resistance
data, to provide a thermal design so that none of the rat-
ings for the IC are exceeded.
(8)
Make sure that the output current and supply voltage do
not exceed the ASO values.
(9)
To ensure reliability, it is recommended that the mode
switching for the motor pass once through the open
mode.
(10) In-rush current
There are no circuits built into these ICs that prevent in-
rush currents. Therefore, it is recommended to place a
current limiting resistor or other physical countermea-
sure.
(11) Factors regarding the thermal, power supply, and
motor conditions
If the potential of the output pin sways greatly and goes
below the potential of ground, the operation of the IC may
malfunction or be adversely affected. In such a case,
place a diode between the output and ground, or other
measure, to prevent this.

(13) The input pins (pins 2 and 10) have temperature-
dependent characteristics. Take the temperature effect
into consideration when using the IC.
(14) To eliminate motor noise, connect a capacitor be-
tween OUT1 (pin 7) and GND and between OUT2 (pin 4)
and GND. Alternatively, connect a capacitor between
OUT1 and OUT2, and also a diode between OUT1 and
GND and between OUT2 and GND (see Fig. 5).
