Overview

TMC249 / TMC249A DATA SHEET (V2.
10 / 2011-Aug-10) 1 TMC249/A – DATASHEET High current microstep stepper motor driver with stallGuard™, protection / diagnostics and SPI Interface TRINAMIC Motion Control GmbH & Co KG Hamburg, Germany ® www.

com 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 LowRDS-ON high efficiency MOSFETs.
It supports more than 6000mA 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...
