Product Information

Back to top
The TMC246 is a dual full bridge driver IC for bipolar stepper motor control applications. The integrated unique sensorless stall detection ( 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 TMC246 an optimum choice for drives, where a high reliability is desired.

The TMC246 is realized in a HVCMOS technology combined with Low-RDS-ON high efficiency MOSFETs ( It gives the choice to operate at high temperature or at high current of up to 1500mA. Its low current consumption and high efficiency together with the miniature package make it a perfect solution for embedded motion control and for battery powered devices.

Internal DACs allow microstepping as well as smart current control. The device can be controlled by a serial interface (SPI™) or by analog / digital input signals. Short circuit, temperature, undervoltage and overvoltage protection are integrated.
