Operation notes
(1)
The quality of these products have been carefully
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)
GND potential
The potential for pin 1 must be kept lower than the poten-
sials ofthe other pins regardless of the circumstances.
(3)
Input pins
Voltage should never be applied to the input pins when
the V
CC
voltage is not applied to the IC. Similarly, when
V
CC
is applied, the voltage on each input pin should be
less than V
CC
and within the guaranteed range for the
electrical characteristics.
(4)
Back-rush voltage
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)
Power dissipation
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)
Power consumption
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)
Current consumption
The ratio of current consumption (I
CC1
versus I
CC2
) is 1 :
2 for the logic section GND (pins 2 and 5) and the power
section GND (pin 8).
