Motor coil
(1) D1 is used to prevent IC destruction caused by reverse-connection. It can be omitted if no problems are expected.
(2) C2 is used to apply a kickback regenerative current when using the IC with the coil current over 500 mA.
(3) When CT is not used, it should be connected to ground.
(4) When RD, ST, and HB are not used, they should be left open.
