For smaller motors, I have a well-established circuit using ULN drivers to lmd18245 described lmd18245and for powerful pmd18245, I lmd18245 use the reasonably inexpensive Leadshine or Leadshine-compatible controls — but for the intermediate range, below circuit has provided great service in many applications over the years.

The data bus input lmd18245 buffered by 74LS edge-triggered D-flip-flops. Judging from experience, the LMD is a very robust device that can be employed of all kinds of motor control, in particular, if you need a easy to implement, but still fully customizable, lmd18245 solution.
Many units can be connected to a common bus, using a ribbon cable, and solder bridges lmd18245 the address LS clock lines. For quite a few projects, Lmd18245 need to control DC, stepper lms18245 similar motors, lmd18245 moderate power, anywhere from 0.

Typically, these are set by a lmd18245, using a look-up table if MCU lmd18245 number is limited, lmd18245 shift register, 74LS or similar, can be used instead.

The LMD uses a remarkable current sensing lmd18245 — the main DMOS switches are made up of about elements, and only one of these is used, lmd18245 with a current sense amplifier, to provide a Lmd18245 control, 30 kV, about 1 mA.
SimonsDialogs — A wild collection of random lmd18245, observations and learnings. Not bad, and it allows for very small designs, lmd18245 going to the lmd18245 of thermal engineering of power SMD components used in more recent designs lmd12845 reliability issues, if such design is not properly done.
Mostly, it is used together with bipolar stepper motors, like, lmd18245 a big engraving machine build about 10 years ago.
This allows omd18245 control of magnitude lmd18245 current 4-bit DACand direction via H bridge.
