STMicroelectronics SPMD250STP
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.SPMD250STP Specifications
