TMC262中文资料Stepper motor driver 5 to 60V, for external P/N-Fets with S/D and SPI Interface, 256 µSteps, CoolStep, StallGuard2 and SpreadCycle.数据手册ADI规格书

描述 Description

The TMC262C drivers for two-phase steppermotors offer an industry-leading featureset, including high-resolution microstepping, sensorless mechanical loadmeasurement, load-adaptive power optimization, and low-resonance chopper operation. Standard SPI™ and STEP/DIRinterfaces simplify communication. TheTMC262 uses four external N- and P-channel dual-MOSFETs for motor currentsup to 10A RMS and up to 60V. Integratedprotection and diagnostic features supportrobust and reliable operation.High integration, high energy efficiencyand small form factor enable miniaturizeddesigns with low external componentcount for cost-effective and highlycompetitive solutions.The new –C device improves motor silenceand adds low side short protection.

APPLICATIONS:

Textile, Sewing Machines Factory Automation Lab Automation Liquid Handling Medical Office Automation Printer and Scanner CCTV, Security ATM, Cash recycler POS Pumps and Valves Heliostat Controller CNC Machines
