TMC236 pdf datasheet

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 efficiency 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 efficiency make the device a perfect solution for embedded motion control and even for battery powered designs.
To test existing designs, consisting of the stepper motor driver L9935, Trinamic provides a small replacement PCB including the more powerfull TMC236 driver IC. An application note (TMC236 to L9935 Adapter.pdf) is available for download.
