The TMC239 is a smart high current 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. It directly drives external MOSFETs for currents up to 6A. This way it reaches an extremely high efficiency and allows driving of a high motor current without cooling measures even at high environment temperatures. With the new chip-scale QFN package a 4A motor driver can be realized on the size of a stamp!
The high motor current makes this device ideal for miniaturized highly dynamic and high torque drive systems.
