Energy-saving, high-resolution microstep 2-phase stepper motor driver with step and direction interface and internal (TMC260, TMC261) or external power amplifier (TMC262) with diagnostics and protection.

• Up to 256 microsteps with the step/direction interface or the SPI™ interface
• coolStep™: store up to 75% of the energy requirement with the help of the automatic load-adaptive motor-current control
• stallGuard2™: precise sensor-free motor-load measurement
• microPlyer: microstep extrapolator gives 256-microstep smoothness with the low frequency of the step input
• spreadCycle: precise chopper algorithm
• Dual-edge step option permits half step frequency, e.g., for optocouplers
• Up to 8 A motor current with external N- & P-channel MOSFET pairs (TMC262)
Up to 1.7 A with integral power-MOS transistors (TMC260 and TMC261)
• Synchronous rectification reduces transistor heating
• Operating voltage of 9 - 60 V (TMC261, TMC262), or 9 - 40 V (TMC260)
• 3.3-V or 5-V interface
• QFN32 package (TMC262) for an extremely small solution with superior thermal performance
• 10 mm x 10 mm TQFP-44 enclosure (TMC260, TMC261)
• Up to 40 mA gate current (TMC262)
• Integrated diagnostics (over-temperature/overload/short circuit)

Applications
• Energy-efficient industrial and commercial stepper motor applications
• Precision two-phase stepper motor drives
• Medical and optical applications
• Robotics

Motor type
• 2-phase stepper motors
