Product Information

Back to top
The TMC236 is a smart power microstepping driver for bipolar stepper motors. It provides an SPI™ interface as well as the classical analog / digital control. A full set of protection and diagnostic features makes this device very rugged. The integrated low-RDS-ON TrenchFET® power MOSFETs give an extremely high effi ciency and allow driving of a high motor current of up to 1.5A per phase without cooling measures even at high environment temperatures. The small footprint and high effi ciency make the device a perfect solution for embedded motion control and even for battery powered designs.
