The STSPIN220 is a stepper motor driver which integrates, in a small VFQFPN 3 x 3 x 1.0 mm package, both control logic and a low RDS(on)power stage. The integrated controller implements PWM current control with fixed OFF time and a microstepping resolution up to 1/256thof a step. 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.
