Product Information

The TMC248 driver for two-phase stepper motors offers a competitive feature set, including 64x micro-stepping, sensorless mechanical load measurement with stall detection, and smart current control. Standard SPI™ and communication via external analog / digital signals are available. The TMC248 drives eight external Low-RDS-ON high efficiency MOSFETs for motor currents up to 7A and up to 36V. Integrated protection and diagnostic features support robust and reliable operation. High integration and small form factor enable miniaturized designs with low external component count for costeffective and highly competitive solutions.
