Stepper Motor Drivers

This discrete MOSFET stepper motor driver enables control of one bipolar stepper motor. It supports a wide 8 V to 50 V operating voltage range and can deliver up to 4 A continuous per phase without a heat sink or forced air flow (6 A max with sufficient additional cooling). The SPI interface allows configuration of the current limiting, step mode (9 step modes from full-step through 1/256-step), decay mode, and stall detection. The driver also provides back-EMF feedback that can be used for more advanced control and stall detection algorithms. Additional features include reverse-voltage, under-voltage, and over-current protection.

This breakout board makes it easy to use Toshiba’s TB67S128FTG microstepping bipolar stepper motor driver, which features adjustable current limiting and microstepping down to 1/128-step. In addition, it has the ability to dynamically select an optimal decay mode by monitoring the actual motor current, and it can automatically reduce the driving current below the full amount when the motor is lightly loaded to minimize power consumption and heat generation. The driver has a wide operating voltage range of 6.5 V to 44 V and can deliver approximately 2.1 A per phase continuously without a heat sink or forced air flow (up to 5 A peak). It features built-in protection against under-voltage, over-current, and over-temperature conditions; our carrier board also adds reverse-voltage protection (up to 40 V).

This is a breakout board for ON Semiconductor’s AMIS-30543 microstepping bipolar stepper motor driver, which features SPI-adjustable current limiting, 11 step modes (from full-step through 1/128-step), back-EMF feedback that can be used for stall detection or optional closed-loop control, and over-current and over-temperature protection. The board operates from 6 V to 30 V and can deliver up to approximately 1.8 A per phase without a heat sink or forced air flow (it is rated for 3 A per coil with sufficient additional cooling).

This is a breakout board for TI’s DRV8834 microstepping bipolar stepper motor driver. It has a pinout and interface that are nearly identical to those of our A4988 carriers, so it can be used as a drop-in replacement for those boards in many applications. The DRV8834 operates from 2.5–10.8 V, allowing stepper motors to be powered with voltages that are too low for other drivers, and can deliver up to approximately 1.5 A per phase continuously without a heat sink or forced air flow (up to 2 A peak). It features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). This board ships with 0.1″ male header pins included but not soldered in.

This version of our DRV8834 Low-Voltage Stepper Motor Driver Carrier ships with male header pins installed, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Please see the DRV8834 Low-Voltage Stepper Motor Driver Carrier product page for more information about the driver.
