Description

Overview

The Tic family of stepper motor controllers makes it easy to add basic control of a bipolar stepper motor to a variety of projects. These versatile, general-purpose modules support six different control interfaces–USB for direct connection to a computer, TTL serial and I²C for use with a microcontroller, RC hobby servo pulses for use in an RC system, analogue voltages for use with a potentiometer or analogue joystick, and quadrature encoder for use with a rotary encoder dial–and offer many settings that can be configured using our free configuration utility (for Windows, Linux, and macOS). This software simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB (a micro-B USB cable is required to connect the Tic to a computer).

The Tic family currently has two members: the Tic T825, which operates from 8.5 V to 45 V, and the Tic T834, which operates from 2.5 V to 10.8 V. Both can deliver up to 1.5 A continuous per phase without a heat sink or forced air flow.

Details for item #3132

The Tic T834 is based on the DRV8834 IC from Texas Instruments. It can operate from 2.5 V to 10.8 V and can deliver up to approximately 1.5 A continuous per phase without a heat sink or forced air flow (the peak current per phase is 2 A). This version is sold with connectors soldered so no soldering is necessary to use it.

FAQs

I want to control a 3.9 V, 600 mA per phase bipolar stepper motor like this, but your Tic T825 stepper motor controller has a minimum operating voltage of 8.5 V. Can I use this controller without damaging the stepper motor?

Yes. To avoid damaging your stepper motor, you want to avoid exceeding the rated current, which is 600 mA in this instance. The Tic T825 stepper motor controller has configurable current limiting, so you can set a limit that is appropriate for your stepper motor. As long as you set the limit below the rated current, you will be within spec for your motor, even if the voltage exceeds the rated voltage. The voltage rating is just the voltage at which each coil draws the rated current, so the coils of your stepper motor will draw 600 mA at 3.9 V. By using a higher voltage along with active current limiting, the current is able to ramp up faster, which lets you achieve higher step rates than you could using the rated voltage.

If you do want to use a lower motor supply voltage for other reasons, consider using the Tic T834, which offers the same features as the T825 and operates from 2.5 V to 10.8 V.
