Motor driver ICs
BA6418N
(9)
Make sure that the output current and supply voltage do
not exceed the ASO values.
(10) Precautions for input mode switching
To ensure reliability, it is recommended that the mode
switching for the motor pass once through the open
mode.
(11) 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.
(12) 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) Minimum operating voltage applied between power
supply (pin 6) and COM (pin 8)
The minimum operating voltage applied between these
pins is 4V at an ambient temperature of 25 C, but the
voltage increases by 8mV (typical) for each degree be-
low 25 C. Keep in mind this negative temperature de-
pendence when setting the voltage at low ambient tem-
peratures.
(14) Thermal shutdown circuit
When the thermal shutdown circuit is activated at the IC
junction temperature of about 175 C (typical), all driver
outputs are turned OFF. There is a temperature differ-
ence of about 15 C (typical) between the temperatures
at which the circuit is activated and deactivated.
(15) To eliminate motor noise, connect a capacitor be-
tween OUT
1
(pin 9) and GND and between OUT
2
(pin 7)
and GND. Alternatively, connect a capacitor between
OUT
1
and OUT
2
, and also a diode between OUT
1
and
GND and between OUT
2
and GND (see Fig. 4).
