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 of up to 4A. (A list of

compatible power MOSFETs is given within the datasheet.) 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 pack-

age 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.

The evaluation can be done with the TMC249 as the only differ-

ence is the additional stallGuard™ feature.
