SI-7510

5-phase stepping motor driver IC with new pentagon driver. The built-in sequencer allows motor to be driven by an external clock(CL) input. Driver will consist of 3 package configuration: Nch power MOS FET array for output stage, and SI-7510+MOS array x 2.

Features

    ・Main supply voltage: cc1=10V to 42V 
    ・Logic supply voltage Vcc2 =3V to 5.5V
    ・Switching between forward (CW) and backward (CCW) regulation
    ・4 phase (Half), 4-5 phase (Full) switching
    ・Enable/Disable switching During Disable, a clock input will automatically sequence to the next level, since the internal counter is in operation
    ・Built charge pump circuit for high-side. This product employs Nch MOS FET for all output stages, and therefore charge pump circuit is built-in for high-side.
    ・Self-excitation constant current control with external Rt/Ct
    ・Maximum output current is dependant on the rating of the MOS FET array used together with the motor driver
      Output current Io=6A SLA5073+SLA5074
      Output current Io=7A SLA5068+SLA5065
