It provides an SPI™ 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® 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 perINTERFACE • 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 SPI™ interface • classical analog interface ELECTRICAL DATA fect solution for embedded motion control and even for battery powered designs. The evaluation can be done with the TMC246, as the only difference is the additional stallGuard™ feature.
