SPMD250STP
2.5 A bipolar stepper motor drive module
Features

Wide supply voltage range Full/Half step drive capability Logic signals TTL/CMOS compatible Programmable motor phase current and chopper frequency Selectable Slow/Fast current decay Synchronization for multimotor applications Remote shut-down Home position indication

Description
The SPMD250STP is a drive module that directly interface a microprocessor to a two phase, bipolar, permanent magnet stepper motors. The phase current is chopper controlled, and the internal phase sequence generation reduces the burden of the controller and it simplifies software development. The SPMD250STP has PowerMOS outputs to significantly reduce both commutation and conduction losses. A further benefit offered by the SPMD250STP is the complete protection of the outputs against any type of shorts.
