2. The power-saving mode is set when the PS pin goes high. In this mode, the voltage of the charge pump
circuit is lowered and the ON resistance of the H bridge driver transistor increases, limiting the current.
In the power-saving mode, the motor cannot turn.
3. It is recommended to connect an external capacitor of 0.22 µF or more between VM and GND to stabilize
the operation.
