SPMD250STP Datasheet (STMicroelectronics) - 2.5 A bipolar stepper motor drive module

SPMD250STP, 2.5 A bipolar stepper motor drive module

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.
