1. D1 is for protection against breakdown in case of reverse connection of power supply and mat is deleted when there
is no problem.
2. C2 is necessary to allow the kick-back regenerative current to flow when C2 is to be used with the coil current of
500mA or more.
3. CT to be connected to GND when not used.
4. RD, ST and HB pins to be OPEN when not used.
