Microstep Driver for up to 1.5A

   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.
