MAIN CHARACTERISTICS

INFO

• high precision micro step sequencer for

smooth motion applications

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.

• 2-phase stepper motor control

• 3-phase stepper motor control

• 9 bit PWM units, 8 bit PWM scaler

• 4 bit PWM sub-modulation for scaling quan-

tization compensation

• PWM frequency programmable

• programmable break-before-make timing

• integrated current measurement ADC (just 2

LM339, 1 LM324 and some RC required)

• integrated current regulation

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.

• manual or automatic microstep to fullstep

switching for higher speeds

• chopSync™ for high velocity operation

ELECTRICAL • operation with 3.3V compatible IOs / 1.5V
