Handling Precautions
CW/CCW/Stop contro circuit
a) At 3ST input, because the input voltage ranges for V
RV
(Reverse mode) and V
STP
(Stop mode) are narrow,
make sure no impedance is caused between the IC V
CC
and GND pins. Do not connect an input resistor to
the 3ST pin as this will cause voltage offset.
b) When controlling the rotation direction using 3ST input, switch the direction from Reverse to Stop mode or
vice versa with V
S
=
0 V; otherwise punch-through current may be generated at output.
Hall amp. circuit
A Hall IC input amplitude of over 400 mV
p-p
causes an output function error. Make sure the amplitude is
within the specified range.
Output circuit
Particular care is necessary in the design of the output, V
S
, V
CC
and GND lines since the IC may be destroyed
due to short circuits between output air contamination faults, or faults caused by improper grounding

(Note 4)
Note 3: Set an appropriate value depending on the motor and use conditions.
Set an appropriate value so that the Hall IC output common-mode input voltage and amplitude fall within the
specified ranges in the Electrical Characteristics table.
Note 4: Be sure to set this bias so that the Hall element output amplitude and common-mode input voltage fall within
the ranges specified in the table of electrical characteristics.
