In bipolar stepper motors, current can flow in both directions; a full-bridge converter is required to drive each of the two windings of a two-phase motor. During motion, the type of electronic control (full step, half step, micro-stepping) and the resulting phase current waveform impact the vibration level, acoustic noise, motion smoothness and sensitivity to resonances.

ST fully supports all these configurations with monolithic motor driver ICs (embedding digital controllers, power devices and protection functions) and for higher power, with a controller and MOSFETs combination approach.
