WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.

FUNCTIONAL DESCRIPTIONS
FORWARD/REVERSE MODE (MODE B& C)
In this mode, the transistor pairs Q2-Q3 and Q1-Q4 work alternatively, changing the output current direction.
When the mode B is selected, Q2 and Q3 are active and Q1 and Q4 are inactive. Therefore A-OUT is at low
level and B-OUT is at high level, with the current flowing from B-OUT to A-OUT through the motor. On the other
hand, when the mode C is selected, the current flows in the reverse direction.
BRAKE/STOP MODE (MODE A)
When the mode A is selected, Q1 and Q3 are inactive and Q2 and Q4 are active. A-OUT and B-OUT are stuck
at low-level; terminals of motor are shorted and the motor is forced to stop.
STANDBY MODE (MODE D)
In this mode, all transistors are inactive and the current through the motor does not flow. When the power supply
voltage is applied to A-V
CC
and B-V
CC
, the supply current is still less than or equal to 1 mA.
