STSPIN220

电机驱动器/控制器, 步进, 1.8V至10V, 1.3A/1输出, VFQFPN-EP-16

The is a stepper motor driver which integrates, in a small QFN 3 x 3 mm package, both control logic and a low RDSon 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.
