6.1.4 TMC249 motor driver
The stepper motor driver used on the TMCM-109 module is the TMC249 chip. This driver is very
dependable, because it provides a variety of protection and diagnostic features, which even can be
read out by the user software. It’s 16 times microstepping gives a quiet and precise motor operation.
A maximum coil current of 5.0A is supported by this driver IC together with the high performance
MOSFETs the module is equipped with.

6.2 Power supply requirements
The TMCM-109 is equipped with a switching voltage regulator that generates the 5V supply voltage for
the digital components of the module from the motor power supply. Because of that only one supply
voltage is needed for the module. The power supply voltage can be 18… 55V DC. Please note that
there is no protection against reverse polarity or too high voltage. The power supply typically should
be within a range of 24 to 48V to achieve highest motor performance. When using supply voltages
near the upper limit, a regulated power supply becomes a must. Please ensure, that enough power
filtering capacitors are provided in the system (2200µF or more recommended), in order to absorb
mechanical energy fed back by the motor in stall conditions. In larger systems a zener diode circuitry
might be required, when motors are operated at high velocities.
The power supply should be designed in a way, that it supplies the nominal motor voltage at the
desired maximum motor power. In no case shall the supply value exceed the upper/lower voltage
limit. To ensure reliable operation of the unit, the power supply has to have a sufficient output
capacitor and the supply cables should have a low resistance, so that the chopper operation does not
lead to an increased power supply ripple directly at the unit. Power supply ripple due to the chopper
operation should be kept at a maximum of a few 100mV.

Therefore we recommend to
keep power supply cables as short as possible
use large diameter for power supply cables
use a robust 2200µF or larger additional filtering capacitor located near to the motor driver
unit, if the distance to the power supply is large (i.e. more than 2-3m)

6.3 Disable
The disable input works as an emergency shutdown. The polarity can be configured using TMCL™.
It is in the user’s responsibility to stop the step impulses or set the velocity to zero before enabling
the motor again, because it would start abruptly or otherwise loose track.
