Description

The STSPIN820 is a stepper motor driver which

integrates, in a small QFN 4 x 4 mm package,

both control logic and a low RDSon power stage.

The integrated controller implements a PWM

current control with fixed OFF time and a

microstepping resolution up to 1/256th of the step.

The device can be forced into a low consumption

state.

The device offers a complete set of protection

features including overcurrent, overtemperature

and short-circuit protection.

QFN 4 x 4 - 24 lead
