Features

The TMC239 is a dual full bridge driver IC for stepper motor control applications. It is realized in a

HVCMOS technology and directly drives eight external Low-RDS-ON high efficiency MOSFETs. The

driver transistors can be chosen depending on output current or environment temperature. Its low

current consumption and high efficiency together with the miniature package make the TMC239 a

perfect solution for embedded motion control and for battery powered devices. It supports more than

3000mA coil current. With additional drivers, motor current and voltage can be increased. Internal

DACs allow microstepping as well as smart current control. The device can be controlled by a serial

interface (SPI™ⁱ) or by analog / digital input signals. Short circuit, temperature and undervoltage

protection is integrated.

Control via SPI with easy-to-use 12 bit protocol or external analog / digital signals

Short circuit and over temperature protection integrated

Status flags for overcurrent, open load, over temperature, temperature pre-warning, undervoltage

Integrated 4 bit DACs allow up to 16 times microstepping via SPI, any resolution via analog control

Mixed decay feature for smooth motor operation

Slope control user programmable to reduce electromagnetic emissions

Chopper frequency programmable via a single capacitor or external clock

Current control allows cool motor and driver operation

Internal open load detector

7V to 30V motor supply voltage

More than 3000mA using 8 external MOS transistors

External drivers can be added for higher motor voltages and higher currents (e.g. 75V, 10A)

Only 4 external PMOS transistors required for unipolar operation

3.3V or 5V operation for digital part

Low power consumption via low RDS-ON power stage

Standby and shutdown mode available
