Features

The TMC249 / TMC249A (1) is a dual full bridge driver IC for bipolar stepper motor control

applications. The TMC249 is realized in a HVCMOS technology and directly drives eight external Low-

RDS-ON high efficiency MOSFETs. It supports more than 4000mA coil current. The low power

dissipation makes the TMC249 an optimum choice for drives, where a high reliability is desired. With

additional drivers, motor current and voltage can be increased. The integrated unique sensorless stall

detection (pat. pend.) StallGuard™ makes it a good choice for applications, where a reference point is

needed, but where a switch is not desired. Its ability to predict an overload makes the TMC249 an

optimum choice for drives, where a high reliability is desired. 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 4000mA using 8 external MOS transistors (e.g. 2.8A RMS)

Sensorless stall detection StallGuard and load measurement integrated

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

Short circuit, overvoltage and overtemperature 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

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

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

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 TMC249 in this datasheet always refers to the TMC249A and the TMC249. The major

differences in the older TMC249 are explicitly marked with “non-A-type”. The TMC249A brings a

number of enhancements and is fully backward compatible to the TMC249.
