The TMC401 converts step/direction signals into SPI datagrams

that can be used to drive a TMC236, TMC239, TMC246 or TMC249

stepper motor driver chip directly. It provides five different

microstep resolutions (from 1/32 to 1/2) as well as two full step

resolution modes. The stallGuard™ bits of a TMC246 or TMC249

motor driver are output on three pins, in order to allow an easy

usage of the stallGuard™ feature. Also the overtemperature

pre-warning bit is output on one extra pin (and can be used to

shut off the driver when there is an overtemperature pre-warn-

ing condition).

The TMC401 also provides a feature that reduces the motor current

to 25% when there have not been any step pulses for at least

one second. This features can be enabled or disabled. Mixed

Decay can also be enabled or disabled using a dedicated pin.

The evaluation board contains the TMC401 and different driver

configurations of the TMC249 wit external MOSFETs.
