(10) ASO

Make sure that the output current and supply voltage do

not exceed the ASO values.

(11) Precautions for input mode switching

To ensure reliability, it is recommended that the mode

switching for the motor pass once through the open

mode.

(12) 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.

(13) 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.

occur if a circuit having an output impedance of

more than a few hundred ohms is connected to pin

4. In this case, connect a capacitor of at least

3300pF.
