Please kindly help to confirm: Does drv8805 or drv8806 match customer motor to replace sla7033.And please help to recommend more cost-effective device。

Thanks a lot!

  • Hi ,

    The DRV8803, DRV8804, DRV8805, and DRV8806 can drive the motor. Other bipolar stepper motor drivers like the DRV8846 or DRV8884 can also be used if the motor is connected in a bipolar configuration. 

    There are a few questions about the application.

    1) What is the voltage at the common pin?
    2) Is current regulation desired?
    3) Will a zener be used to increase the decay?
    4) Is using the motor in bipolar an option?

    Another option is the TPL7407L, although the device does not have the integrated protection features of the DRV88xx devices (overcurrent, short-circuitr, under voltage, and overtemperature with fault indicating output).
