| POWER DR I V E R F O R S T E P P E R M O T O R S I N T E G R A T E D C I R C U ITS TMC2 46 Micr oste p Dr iver for up to 1.5A wi th s tall Guar dTM M A IN CH A R AC T ER IS T IC S INFO The TMC246 is a smart power microstepping driver for bipolar stepper motors. The integrated unique sensorless stall detection stallGuardTM makes it a good choice for applications where a reference point is needed, but where a switch cannot be used. The ability to predict an overload makes the TMC246 an optimum choice for drives, where a high reliability is desired. It provides an SPITM interface as well as the classical analog / digital control. A full set of protection and diagnostic features makes this device very rugged. The integrated low-RDS-ON TrenchFET(R) power MOSFETs give an extremely high efficiency and allow driving of a high motor current of up to 1.5A per phase without cooling measures even at high environment temperatures. The small footprint and high efficiency make the device a perfect solution for embedded motion control and even for battery PACKAGE ELECTRICAL DATA INTERFACE * sensorless stall detection StallGuardTM * full protection and diagnostics * low power dissipation * 16 times microstepping via SPI, 64 times using additional shift register, even more via analog control * mixed decay for smooth operation * programmable slope control for low EME * internal or external chopper clock * standby and shutdown mode * easy-to-use SPITM interface * classical analog interface * up to 1500 mA coil current (peak) * 7V to 34V motor supply (TMC246A) * 3.3V or 5V operation for digital part * standard PQFP-44 package * RoHS compliant powered designs.
