It drives external power stages via four pre-driver half-bridge outputs, so the actual motor current capability depends on the external MOSFETs you pair it with — the controller itself handles the sequencing and microstepping logic. Step resolution goes from full-step down to 1/128 microstepping, which means you can smooth out low-speed vibration and position the rotor in 256 microsteps per full electrical cycle without an external interpolator. The digital motion engine on-chip manages acceleration profiles and target position — the host MCU just sends SPI commands. The surface-mount footprint is the same as the L6480HTR variant — the only difference is the shipping format: tube vs tape-and-reel.","metaTitle":"STMicroelectronics L6480H STSPIN L64 Stepper Motor Driver","metaDescription":"STMicroelectronics L6480H stepper motor controller, SPI interface, 1/128 microstepping, 3.3V/5V supply.
