The STPMDRV-404 is a high performance, low cost
micro-stepping driver that incorporates advanced surface mount and ASIC
technology. The STPMDRV-404 is small, easy to interface and use, yet
powerful enough to handle the most demanding applications.
The STPMDRV-404 has 14 different resolutions (both in binary and
decimal) built into the driver. The development
of proprietary circuits has minimized ripple current while maintaining a
25 KHz chopping rate. This
prevents additional motor heating that is common with drivers requiring
higher chopping rates
The low inductance stepper motors can be used to
improve high speed performance and system efficiency.
