TMC262 - TRINAMIC

TMC262 cost-effective stepper driver

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 MOSFET.
