Recommended Application Circuit
Note: It is recommended to add bypass capacitors as required.
The values of external constants are example recommended values. For values under different input
conditions, see the above-mentioned recommended operating conditions.
(The following shows an example when fcho = 501 Hz (CR frequency = 800 kHz and constant-current
limiter = 2.27 A) with serial signals placed in initial status.)
SGND
Make sure that all gound pins are connected to the same ground rail.
STROBE, CLK, and DATA must be tied to LGND if serial input is not used for settings or motor control.
Because there may be short circuits between outputs, to supply, or to ground, be careful when designing
