TMC249A-SA

The TMC249A-SA is a smart high current Micro Stepping Driver for bi-polar stepper motors. The integrated unique sensorless stall detection stallGuard™ makes it a good choice for applications, where a reference point is needed, but where a switch cannot be used. The ability to predict an overload makes this an optimum choice for drives, where a high reliability is desired. It provides an SPI™ interface as well as the classical analogue/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. The high motor current makes this device ideal for miniaturized highly dynamic and high torque drive systems.
