STSPIN820

STSPIN820 is an advanced 256 microsteps integrated motor driver with step-clock and direction interface. 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. Typical applications include 3D printers, medical equipment, industrial 2D printers, textile and sewing machines, CCTV, security and dome cameras, ATM and cash handling machines, office and home automation, POS and robotics.
