Stand-Alone Stepper Motor Driver with Step/Direction (1,2A/46V)
The TMC2100 is one of 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 1.2A RMS (TMC2100-LA) or 1.4A RMS (TMC2100-TA) continuously or 2.5A 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.
