POWER DRIVER FOR STEPPER MOTORS

INTEGRATED CIRCUITS

TMC236

Microstep Driver for

up to 1.5A

MAIN CHARACTERISTICS

INFO The TMC236 is a smart power 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 diag-

nostic 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 environ-

ment temperatures.

• 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

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

fect solution for embedded motion control and even for battery

powered designs.

INTERFACE • easy-to-use SPI™ interface

• classical analog interface

ELECTRICAL • up to 1500 mA coil current (peak)

DATA

The evaluation can be done with the TMC246, as the only differ-

ence is the additional stallGuard™ feature.

• 7V to 34V motor supply (TMC236A)

• 3.3V or 5V operation for digital part

PACKAGE • standard PQFP-44 package

• RoHS compliant
