Regulated or Unregulated Power Supply
Both regulated and unregulated power supplies can be used to supply the driver. However,
unregulated power supplies are preferred due to their ability to withstand current surge. If regulated
power supplies (such as most switching supplies.) are indeed used, it is important to have large
current output rating to avoid problems like current clamp. On the other hand, if unregulated supply is
used, one may use a power supply of lower current rating than that of motor

unregulated supply only during the ON duration, but not during the OFF duration. Therefore, the

It is recommended to have multiple drivers to share one power supply to reduce cost, if the supply has
