POWER DRIVER FOR STEPPER MOTORS

INTEGRATED CIRCUITS

TMC246

Microstep Driver for

up to 1.5A

with stallGuard™

MAIN CHARACTERISTICS

INFO The TMC246 is a smart power microstepping driver for bipolar

stepper motors. The integrated unique sensorless stall detec-

tion stallGuard™ makes it a good choice for applications where

a reference point is needed, but where a switch cannot be

used. The ability to predict an overload makes the TMC246 an

optimum choice for drives, where a high reliability is desired.

It provides an SPI™ interface as well as the classical analog /

digital control. A full set of protection and diagnostic features

makes this device very rugged. The integrated low-RDS-ON

TrenchFET® power MOSFETs give an extremely high efficiency

and allow driving of a high motor current of up to 1.5A per

phase without cooling measures even at high environment

temperatures.

• sensorless stall detection StallGuard™

• full protection and diagnostics

• low power dissipation

• 16 times microstepping via SPI,

64 times using additional shift register,

even more via analog control

• mixed decay for smooth operation

• programmable slope control for low EME

• internal or external chopper clock

• standby and shutdown mode

INTERFACE • easy-to-use SPI™ interface

• classical analog interface

ELECTRICAL • up to 1500 mA coil current (peak)

DATA

• 7V to 34V motor supply (TMC246A)

• 3.3V or 5V operation for digital part

PACKAGE • standard PQFP-44 package

• RoHS compliant

The small footprint and high efficiency make the device a per-

fect solution for embedded motion control and even for battery

powered designs.
