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.

s OPERATIONS
1. Forward and Reverse
Switching control mode A or B pairs Q2 and Q3, or Q1 and Q4, respectively, while reversing the supply current to the motor for each switching. When Q2 and Q3 are in use, B-OUT and A-OUT are High level and Low level, respectively. In this case, current flows B-OUT→ motor → A-OUT, causing forward operation as described in the table below. When Q1 and Q4 are in use, current flows in the reverse direction to the above flow, causing reverse motor operation.
2. Brake
Control mode C operates Q2 and Q4 while stopping Q1 and Q3. Since A-OUT and B-OUT are held at Low level, both poles of the motor are short-circuited and the motor is stopped.
3. Stand-by
Control mode D turns Q1 to Q4 OFF and the motor has no current flow. In this mode, the power supply current is less than 100 µA.

Note : If input voltage is applied when power is not supplied, over-current flows into the device via the input pins. In this case, connect a resistor of at least 1 kΩ in series with the input pins to prevent passage of a large current.
