The STSPIN220 is a stepper motor driver which integrates, in a small QFN 3 x 3 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 1/256th of 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.
●Key Features
