POWER DRIVER FOR STEPPER MOTORS

INTEGRATED CIRCUITS

TMC239

Microstep Driver

for External MOSFETs

for up to 4A

MAIN CHARACTERISTICS

INFO The TMC239 is a smart high current microstepping driver for

bipolar stepper motors. 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. It directly

drives external MOSFETs for currents of up to 4A. (A list of

compatible power MOSFETs is given within the datasheet.) This

way it reaches an extremely high efficiency and allows driving

of a high motor current without cooling measures even at high

environment temperatures. With the new chip-scale QFN pack-

age a 4A motor driver can be realized on the size of a stamp!

• 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

The high motor current makes this device ideal for miniaturized

highly dynamic and high torque drive systems.

ELECTRICAL • up to 4000 mA coil current (peak) with

DATA

just 4 external dual MOSFETS

The evaluation can be done with the TMC249 as the only differ-

ence is the additional stallGuard™ feature.

• 7V to 34V motor supply (TMC239A),

up to 60V using a few add. components

• higher current / voltage using additional

gate drivers

• 3.3V or 5V operation for digital part

PACKAGE • standard SO28 package

• chip size QFN32 package

• RoHS compliant
