Packing

STSPIN220

VFQFPN 3x3x1.0

16L

The integrated controller implements PWM current control with fixed OFF time and a

microstepping resolution up to 1/256^thof a step.

Tape & reel

The device is designed to operate in battery-powered scenarios and can be forced

into a zero-consumption state, allowing a significant increase in battery life.

The device offers a complete set of protection features including overcurrent,

overtemperature and short-circuit protection.
