Features

The TMC239 / TMC239A (1) is a dual full bridge driver IC for bipolar stepper motor control

applications. The TMC239 is realized in a HVCMOS technology and directly drives eight external Low-

RDS-ON high efficiency MOSFETs. It supports more than 6000mA coil current. The low power

dissipation makes the TMC239 an optimum choice for drives, where a high reliability is desired. With

additional drivers, motor current and voltage can be increased. The driver transistors can be chosen

depending on output current or environment temperature. 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, undervoltage and overvoltage protection are integrated.

More than 6000mA using 8 external MOS transistors (e.g. 4A RMS)

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

Short circuit and over temperature protection integrated

Overvoltage protection integrated (A-type)

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

(for up to 64 microsteps via SPI see last manual page)

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

7V to 34V motor supply voltage (A-type)

up to 58V motor supply voltage using a few additional low cost components

External drivers can be added for higher motor voltages and higher currents (e.g. 50V, 5A)

Only 4 external PMOS transistors required for unipolar operation

3.3V or 5V operation for digital part

Low power dissipation via low RDS-ON power stage

Standby and shutdown mode available

Choice of SO28 or chip size MLF package

(1) The term TMC239 in this datasheet always refers to the TMC239A and the TMC239. The major

differences in the older TMC239 are explicitly marked with “non-A-type”. The TMC239A brings a

number of enhancements and is fully backward compatible to the TMC239.
