Application Circuit Example
Note 1: Utmost care is necessary in the design of the output, V
Note 2: The above application circuit including constant values is provided only as a guide. Since each value may vary depending on the motor type, the optimal values must be determined experimentally.
Note 3: C
Note 4: A Schottky barrier diode (SBD; Toshiba CMS15) must be connected externally between W and GND to ensure smooth current recovery upon output switching.
