TMC248 Micro-Stepping Motor Drivers

Trinamic's TMC248 are smart power micro-stepping motor drivers with a PWM interface for absolute noiseless motor-control at low-velocities

Image of Trinamic Motion Control's TMC248 Micro-Stepping Motor DriversThe TMC248 from Trinamic is a smart, high-current micro-stepping driver for bipolar stepper motors. With it's PWM interface it allows for completely noiseless stepper-motor control. Controlled via SPI, the integrated unique sensorless stall detection technology, stallGuard™, 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 TMC248 an optimum choice for drives where high-reliability is desired. It includes an SPI interface as well as traditional analog/digital control.

A full-set of protection and diagnostic features makes this device very rugged. It directly drives external MOSFETs for currents up to 6 A. This level of integration enables extremely-high-efficiency and allows driving of a high-motor current without cooling measures, even at high-environment temperatures. With the chip-scale QFN package, a 4 A motor driver can be realized on the size of a postage stamp. The high-motor current makes this device ideal for miniaturized, highly-dynamic and high-torque drive systems.
