CAUTIONS
Since pass current of 2 to 4A flows from the power supply to the
GND for the period of 2 to 4 s when a mode is switched to
another, be sure to put the capacitance of 10 to 100 F between
the output power supply and the GND.
When the motor back electromotive force is large with the brakes
applied, for example, malfunction may occur in internal parasitic Di.
If flyback current of 1A or more flows, add Schottky Di to the
portion between the output and the GND.
When the IC is used at a high speed for PWM, etc., note that
switching of output results in delay of approx. 10 s.
