The smd232 power drive is an absolutely economical driver for all common 2-phase hybrid step motors, especially for small motors up to NEMA 17 (40mm flange) size.
The electronic design features very little heat dissipation. For this reason a very compact drive card could be realised.
The drive is suitable for industrial applications. Consequently cheap interconnectors or jumpers for settings were avoided. Especially life time (MTBF) relevant components are of high quality. The signal interface has galvanic isolation with opto isolators. Cable shield connections are available for EMI protection.

The OEM device technology is the main application field for the smd232. Usually the smd232 is mounted inside the OEM device in open frame technology. For simple and fast mounting the power drive can be inserted in a DIN-rail clip module.
