Note 1: Figure 3 shows the basic application circuit.
Note 2: Utmost care is necessary in the design of the output, V
Note 3: Be careful when switching the input because rush current may occur.
Note 4: The IC functions cannot be guaranteed when turning power on of off.

Basic application circuit
Additional diode
Optimum values of the C, R depend on the inherent constant of a motor and parasitic C, R values around the
circuit.
When switching, stop mode should be entered or current limitation resister R should be inserted.
Before using the IC for application, check that there are no problems.

by short-circuiting between outputs, air contamination faults, or faults due to improper grounding, or by
short-circuiting between contiguous pins.
If the braking operation is so loose, connect a additional diode between each output to GND. (See
Figure 4)
electromotive suppression diode may be damaged by this pulse. In such a case connect a additional
diode between each output to V
