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.
TMC262主要特性和優(yōu)勢(shì):
High Current up to 8A Motor current using external (N&P) MOSFETs.
Highest Voltage up to 60V DC operating voltage
Highest Resolution up to 256 microsteps per full step
Smallest Size 5x5mm QFN32 package
Low Power Dissipation synchronous rectification
EMI-optimized slope & current controlled gate drivers
Protection & Diagnostics overcurrent, short to GND, overtemperature & undervoltage
stallGuard2™ high precision sensorless motor load detection
coolStep™ load dependent current control for energy savings up to 75%
microPlyer™ microstep interpolation for increased smoothness with coarse step inputs.
spreadCycle™ high-precision chopper for best current sine wave form and zero crossing

評(píng)估板TMC262–EVAL
Evaluation board for the TMC262 stepper motor driver IC with coolStep
評(píng)估板TMC262–EVAL主要特性:
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!
