【文字介紹】

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.
