The new stepper motor drivers TMC24x are pin- and function compatible for the TMC23x drivers, and they are also the only ones in the world offering the StallGuard? function, with sensorless load angle measurement and motor blocking recognition
Stepper motor drivers capable of micro-steps and with digital interface, integrated 2 bit DAC and StallGuard? for bipolar 2 phase stepper motors
Bi-directional SPI control interface for micro step process and diagnosis
Fully protected unit (short circuit, excess temperature, excess temperature prior warning, open load)
Diagnostic functions (short circuit, excess temperature, excess temperature prior warning, open load)
The TMC246 integrates an efficient MOSFET end stage with low power intake and heat generation for currents of up to 1.5 A per phase
The TMC249 offers a simple connection of external MOSFETs (4*P-MOS + 4*N-MOS) for currents up to 4 A per phase or up to 10 A and higher voltage with additional gate drivers
