1 Principles of Operation
The TMC2160 driver chip is an intelligent power component interfacing between a motion controller
and a high-power stepper motor. It uses stealthChop, dcStep, coolStep, and stallGuard2 automatically
to optimize every motor movement. The TMC2160 ideally extends the TMC2100 and TMC2130 family to
higher voltages and higher motor currents.
THE TMC2160 OFFERS TWO BASIC MODES OF OPERATION:
MODE 1: Step & Direction Driver
An external high-performance S-ramp motion controller like the TMC4361 or a central CPU generates
step & direction signals synchronized to other components like additional motors within the system.
The TMC2160 takes care of intelligent current and mode control and delivers feedback on the state of
the motor. The microPlyer automatically smoothens motion.
MODE 2: Simple Step & Direction Driver
The TMC2160 positions the motor based on step & direction signals. The microPlyer automatically
smoothens motion. No CPU interaction is required; configuration is done by hardware pins. Basic
standby current control can be done by the TMC2160. Optional feedback signals allow error detection
and synchronization. Enable this mode by tying pin SPI_MODE low.
