TMC2130-LA-T describes that TMC2130 is a high-performance driver IC used for two-phase stepper motors. Standard SPI and STEP/DIR simplify communication. TRINAMIC's precise StealthChop chopper ensures noise free operation, combined with the highest efficiency and optimal motor torque. CoolStep can reduce energy consumption by up to 75%. DcStep drives high loads as quickly as possible without causing step loss. The integrated power MOSFET can handle motor currents up to 1.2A RMS (QFN package)/1.4A RMS (TQFP) or 2.5A short-term peak current per coil. The protection and diagnostic functions support robust and reliable operation. The most advanced stepper motor driver in the industry can achieve miniaturization design with a small number of external components, enabling cost-effective and highly competitive solutions.
TMC2130-LA-T applications: textile, sewing machines, factory and laboratory automation, 3D printers, liquid processing, medical office automation, closed-circuit television, secure ATMs, cash recovery machines, POS pumps and valves
