Caution for using
•
•
Utmost care is necessary in the design of the output, V
short-circuiting between outputs, air contamination faults, or faults due to improper grounding, or by
short-circuiting between contiguous pins.
The IC may be destroyed when mounted in the wrong orientation. Thus, please mount it with great care.
Note 1: A power supply capacitor should be connected between V
Note 2: C2 should be connected as close as possible to S-GND.
Note 3: When the power is turned on, set SB for low (standby mode) or IN1 and IN2 for low (stop mode).
Note 4: Avoid connecting the resistor to detect the motor current. If necessary, connect the resistor to V
