TRINAMIC Motion Control unveiled a single-chip motor driver with StealthChop technology to enable virtually silent operation. Serving two-phase stepper motors up to 1.2A RMS in a voltage range from 1.8V to 11V DC, the TMC2300 offers very low power consumption for an extended battery life.

TMC2300 features include:

-StealthChop2, a high-precision algorithm that produces drive waveforms, which enable motors to be nearly inaudible

-StallGuard, a motor load measurement to perform sensorless homing and detect mechanical obstacles

-CoolStep Sensorless, a load-dependent current control to optimize the motor's energy consumption on the fly, enabling energy savings of up to 80 percent over conventional motor drives

-A standby current draw of less than 50nA (typ)

-Single wire UART and Step/Dir interfaces

-Up to 256x microstepping

-Available in a compact QFN20 (3x3) package
