Product Details
Description
The TMC262 is the first energy efficient high current high precision microstepping driver IC for bipolar stepper motors. The unique high resolution sensorless load detection stallGuard2™ is used to for the world’s first integrated load dependent current control feature called coolStep™ The ability to read out the load and detect an overload makes the TMC262 an optimum choice for drives where a high reliability is desired at a low cost. The new patented spreadCycle PWM mixed decay chopper scheme ensures best zero crossing performance as well as high speed operation. The TMC262 can be driven with Step & Direction signals as well as by serial SPI™ interface. Using the microPlyer allows to operate the motor with highest 256 µStep smoothness reducing the input frequency to 16 ?Steps. A full set of protection and diagnostic features makes this device very rugged. It directly drives external MOSFETs for currents of up to 8A. This way it reaches highest energy efficiency and allows driving of a high motor current without cooling measures even at high environment temperatures.

TMC262-EVAL
|
The evaluation board TMC429+TMC26x-EVAL provides an excellent, simple and cost efficient device to explore the latest generation of TRINAMIC stepper motor chipsets. The board contains the 3-axes motion controller TMC429, the three coolStep™ stepper motor drivers TMC260, TMC261 and TMC262 as well as the incremental encoder interface TMC424. You will learn everything about the usage and features of the chipset (coolStep™, stallGuard2™, 256x µstepping, spreadCycle chopper, etc.) and get the possibility to explore your stepper motor motion control application. The evaluation PC-software gives access to every single bit of the chipset. Communication is possible either via USB (virtual COM port) or via RS232. The TMC429+TMC26x-EVAL is a complete “plug and play” solution. It comes with the evaluation software, a USB cable and all relevant pluggable screw connectors. Additionally only a PC, one to three stepper motors and a power supply are required. |
