BLOCK DIAGRAM
The TMC2100 is TRINAMICs most
autonomous driver IC. This small and
intelligent standalone driver for two phase
stepper motors offers market-leading
features while being configured by seven
pins only. CPU interaction is not required.
Drive the motor via Step and Direction
signals.
TRINAMICs
sophisticated
stealthChop chopper ensures noiseless
operation combined with efficiency and
best motor torque. Integrated power
MOSFETs handle motor currents up to 1.2 A
RMS continuously or 2.5 A short time peak
current per coil. For saving energy, the
TMC2100 provides standstill current
reduction. Protection and diagnostic
features support robust and reliable
operation. The TMC2100 enables
miniaturized designs with low external
component count for cost-effective and
highly competitive solutions.
