TMC246B

TMC246 / TMC246A / TMC246B DATA SHEET (V2.11 / 2018-Mar-01) 1 TMC246/B – DATA SHEET High current microstep stepper motor driver with stallGuard™, protection / diagnostics and SPI Interface TRINAMIC® Motion Control GmbH & Co KG Hamburg, Germany WWW.TRINAMIC.COM Features The TMC246 / TMC246A / TMC246B (1) is a dual full bridge driver IC for bipolar stepper motor control applications. 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 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 (pat. pend.). It allows driving a coil current of up to 1500mA even at high environment temperatures. Its low current consumption and high efficiency together with the miniature package make it a perfect so...
