TMC2660-EVAL

The new TMC2660 integrates both a pre-driver for real-time calculation of motor coil current values, and power MOSFETS for amplification of coil outputs to directly drive an external motor.

Packaged in a single multi-chip module, the integrated driver/amplifier achieves the lowest power dissipation currently available for a 4A stepper motor driver. With an Rds(on) of 65mΩ, the TMC2660 dissipates just 2.8W at 4A, an 85% reduction compared with the most competitive solution previously available. The new device’s minimal power dissipation eliminates the need for a heat sink, enabling highly dense board designs and reduced component count and cost.
