概述

  • High Motor Current up to 10A using external (N&P) MOSFETs.
  • Highest Voltage 5V to 60V DC; more w. ext. gate driver
  • Highest Resolution up to 256 microsteps per full step
  • Small Size 5x5mm QFN32 package
  • Low Power Dissipation synchronous rectification
  • Protection & Diagnostics short to GND, overtemperature & undervoltage; short to VS & overcurrent
  • Stand Alone option
  • EMI-optimized slope & current controlled gate drivers
  • StallGuard2™ high precision sensorless motor load detection
  • CoolStep™ load dependent current control saves up to 75%
  • MicroPlyer™ 256 microstep smoothness with 1/16 step input.
  • SpreadCycle™ high-precision chopper for best current sine wave form and zero crossing
  • Improved Silent Motor operation

The TMC262C drivers for two-phase stepper motors offer 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 uses four external N- and P-channel dual-MOSFETs for motor currents up to 10A RMS 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. The new –C device improves motor silence and adds low side short protection.
