Pouya,
According to https://www.orientalmotor.com/stepper-motors/technology/2-phase-vs-5-phase-stepper-motors.html , the 5 phase motor needs 5 half bridges. You can select multi-half bridges drivers, DRV8906..., to drive it.
Also, for 2 phase stepper motor, DRV8889; DRV8846... stepper motor driver offers micro-step setting which can help the motor running smoothly.
POUYA,
si-7510 sequencer solution uses two SLA5074 devices as the motor driver. In this case, DRV8910 can replace two SLA5074 devices. DRV8910 or SLA5074 is a motor driver product for us. Si-7510 sequencer is a controller. For us, it is not motor driver products. That is why you cannot find a similar device in brush and stepper motor product line to compare with Si-7510..
BTW, for a bipolar stepper motor, the control sequence could be integrated in some of motor driver devices because of its high volume. Such as: DRV8825...
