Regulator
INFO _{The TMC332 is a high precision micro step sequencer with}
integrated PWM units. Internal micro step counters with pro-
grammable step width make the handling of the physical units
comfortable. The TMC428 step direction interface of the TMC332
is directly compatible to the driver chain interface of the TMC428
motion controller. The other step direction interface is a classical
two wire step direction interface. Parameterizing of the TMC332
takes place over a common SPI micro controller interface.
The integrated sine wave look up table can output either 2 sine
waves with a phase shift of 90° for 2-phase stepper motors or 3
sine waves with +/- 120° phase shift for 3-phase motors.
The gate control block of the TMC332 provides the gate control
signals for the power stage half bridges, including programma-
ble break before make timing and over current protection. Incre-
mental encoders (ABN) to evaluate the physical motor position
can be connected to the TMC332. The TMC332 also contains a
current measurement unit and a current regulator, requiring only
a few inexpensive external components. Switching to fullstep
and the chopSync™ feature allow high velocity operation.
