/a>Motor Drive” title=”Motor Drive”>Motor Drive” title=”Motor Drive”>Motor Drive, with industry-leading features including high-resolution microstepping, sensorless mechanical load measurement, and load adaptation Power optimization, low resonance chopper operation, standard PI and STEP/DIR interfaces simplify communication. TMC262 can drive four external N-channel and P-channel dual MOSFET, motor current up to 8A and 60V, mainly used in sewing machines, factory automation , Printers and Scanners, Office Automation, Medical Equipment, Liquid Handling, ATM and POS, etc. This paper introduces the main features and advantages of TMC262, block diagram, application block diagram and circuit diagram of high voltage and high current power stage and evaluation board TMC262-EVAL main features, applications Block diagram, circuit diagram and PCB component layout.

The TMC262 driver for two-phase stepper motors offers an industry-leading feature set, including high-resolution microstepping, sensorless mechanical load measurement, load-adaptive power optimization, and low-resonance chopper operation. Standard SPI™ and STEP/DIR interfaces simplify communication. The TMC262 drives four external N- and Pchannel dual MOSFETs for motor currents up to 8A and up to 60V. Integrated protection and diagnostic features support robust and reliable operation.

High integration, high energy efficiency and small form factor enable miniaturized designs with low external component count for cost-effective and highly competitive solutions.

Evaluation Board TMC262–EVAL

Evaluation board for the TMC262 stepper motor driver IC with coolStep

Evaluation board TMC262–EVAL main features:

The TMC262 evaluation board features a TMC262 with external power MOSFETs plus a microcontroller, which allows interfacing to a PC for visualization and control of all parameters. The motor can be operated via the step and direction interface both, using an external source, and using the integrated microcontroller as a step generator.

The TMC262-EVAL allows you to explore all functions of the TMC262. The evaluation board comes with a PC software which gives you access to every function of the driver. It comes along with a Step&Direction interface, a RS232 and a USB port. The TMC262 -Eval is a complete “plug and play” solution, additionally only a motor, a PC and a power supply are required!

Evaluation Board TMC262–EVAL Highlights:

 Evaluate all features of the TMC262

 Use stallGuard2™ with your motor

 Use coolStep™ with your motor

 Control all parameters from a PC using special software or TMCL-PC

 Motor current can be set to up to 1A, 2A or up to 4A (soldering jumper) via on-board sense resistors

 Supply voltage up to 40V (MOSFETs can be exchanged against 60V 2A types)
