5 Phase Stepper Motor Driver Circuit



The compact 5 Phase stepper driver project can handle motor up to 3.5amps supply 12-30V DC, driver has facility to set the load current, driver provides half stepping and full stepping, and easy to drive with step and direction pulse, trimmer pot provided to set the current, The SI-7510 is a pre-driver IC for driving 5-phase stepper motors wound in the New Pentagon configuration (driver circuit design patented by Oriental Motor Co., Ltd.). Direct external control of motor driving functions are synchronized by the built-in sequencer to an applied clock input (CL) signal. The SI-7510 drive is implemented with a user-configurable output stage consisting of dual N-channel power MOSFETs. This results in lower thermal resistance and greater efficiency.
