Ic Driver Motor Stepper
Gate driver ICs for stepper motors allow for flexible designs with a high current profile using external MOSFETs. Designed with a predriver offering full diagnostics via SPI, stepper gate drivers are ideal for saving time and cost by reducing design complexity. With industry-leading current control, all stepper predrivers by Trinamic offer smooth and precise microstepping while improving reliability and robustness of overall system design.
Dedicated motion and interface controllers for stepper motors offload the MCU from real-time critical tasks, calculating ramping and positioning in proven, integrated hardware that's safe and secure. The single bi-directional interface SPI for motion commands and diagnostics keeps the count of required lead traces low, enabling extremely miniaturized and lean designs. Some also support S/D to simplify control of stepper motors.
EtherCAT is the high-performance, low-cost, and easy to use industrial Ethernet technology with a flexible topology. Using Trinamic's EtherCAT Slave Controller ICs, this powerful interface can be combined with leading-edge motor and motion control. The chips connect peripherals optimized for embedded motion and motor control applications to the fast fieldbus, allowing for accurate synchronization of distributed drives.
BLDC motors are increasingly being used in EMC-critical applications and applications with the highest requirements for energy-efficiency. Due to their sinewave commutation, brushless DC motors form silent and efficient drives for heating and ventilation. Equipped with a high-resolution feedback system and field oriented control, Trinamic's BLDC predriver ICs are the best solution for powerful drives.
Trinamic's DC motor driver ICs integrate a highly efficient power stage with internal charge pump, delivering best-in-class RDSon resistance. Even at low supply voltages, the tiny motor driver chips provide high current for best results. With full control via UART, protection and diagnostics allow for robust and reliable operation of DC drives, supporting cost-effective system designs with efficient and reliable operation.
Ideal for high temperature applications such as headlamp leveling/bending and engine management motion control, the AMT49700 is versatile in that it is also suitable for other automotive stepper applications such as HVAC flap and valves.
The current regulator operates with fixed frequency PWM and uses adaptive mixed current decay to reduce audible motor noise and increase step accuracy. The current in each phase of the motor is controlled through a DMOS full-bridge using synchronous rectification to improve power dissipation. Internal circuits and timers prevent cross-conduction and shoot through when switching between high-side and low-side drives.
Stepper motor drivers are specifically designed to drive stepper motors, which are capable of continuous rotation with precise position control, even without a feedback system. Our stepper motor drivers offer adjustable current control and multiple step resolutions, and they feature built-in translators that allow a stepper motor to be controlled with simple step and direction inputs. These modules are generally basic carrier boards for a variety of stepper motor driver ICs that offer low-level interfaces like inputs for directly initiating each step. An external microcontroller is typically required for generating these low-level signals.
These breakout boards for the MPS MP6500 bipolar stepper motor driver feature adjustable current limiting, over-current and over-temperature protection, and four microstep resolutions (down to 1/8-step). They operate from 4.5 V to 35 V and can deliver approximately 1.5 A per phase without a heat sink (driver is rated for up to 2.5 A per coil).
These Black Edition driverse are higher-performance drop-in replacements for the original A4988 stepper motor driver carrier. They feature a four-layer PCB for better thermal performance, allowing the A4988 microstepping bipolar stepper motor driver to deliver approximately 20% more current than our two-layer version.
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 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.
Back in my days working in an optics lab, we would typically use stepper motors to drive sensitive translational and goniometer stages for gathering spatially and spectrally resolved measurements. We always used stepper motors for these applications, thanks to their low hysteresis and fine resolution. Any of these stepper motors requires a driver to move a stage in the desired direction.
Common stepper motors can be classified as unipolar and bipolar devices, referring primarily to the configuration of the coil windings in each stator. At the most basic level, these motors work in the same way; electromagnets are turned on in a consecutive manner to rotate the shaft to the desired position. These motors are ideal for applications that require precise position control; they should not be used if high speed is required. These stepper motors include variable reluctance, hybrid synchronous, and permanent magnet motors.
Typical motors have two phases in order to reduce the lead count. The rotor can have stacked north and south poles along the rotor shaft (so-called can construction) or fine teeth along the axis of the shaft; the angular separation between these regions on the shaft determines the angular resolution of the stepper motor.
Although the simplest way to build a stepper motor control circuit for a unipolar motor involves a 555 timer and some D flip-flops (or H-bridges for bipolar motors), there are many integrated ICs that provide the same capabilities in a low cost, compact package.
The AN44069A-VF stepper motor driver from Panasonic is ideal for driving bipolar stepper motors with 37 V output and 1.5 A constant current sourcing. This IC includes a chopper circuit to limit the current output and a PWM oscillator with two available frequencies for near continuous driving. This driver is ideal for basic stepper motors that do not require extremely precise position control (i.e., microstepping) or high torque.
The STK672-630CN-E constant current stepper motor driver from ON Semiconductor is designed for use with 2-phase unipolar stepper motors. This driver provides higher voltage output (46 V) and current output (2.2 A) than the previous component. The motor step rate is controlled with an external clock circuit, providing flexible speed control.
There are a large number of stepper motor drivers available on the market, which can make it difficult to determine which driver is best for your particular stepper motor. Octopart gives you access to a range of stepper motors and stepper motor driver options. Try using our Part Selector guide to determine the best option for your next product.
Toshiba offers various stepping motor drivers that deliver the substantial benefits of AGC. Stepping motor drivers with a clock input and those with a phase input are both available.

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). The EasyDriver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors.
This EasyDriver V4.5 has been co-designed with Brian Schmalz. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.
