STMicroelectronics STSPIN820 Stepper Motor Driver

STMicroelectronics STSPIN820 Stepper Motor Driver integrates control logic, a low RDSon power stage, and is housed in a small QFN 4x4mm package. The STSPIN820 stepper motor driver's integrated controller implements a PWM current control with fixed OFF time and a microstepping resolution up to 1/256th of the step. This stepper motor driver can be forced into a low consumption state and offers protection features like overcurrent, overtemperature, and short-circuit protection. Typical applications include 3D printers, medical equipment, POS, robotics, industrial 2D printers, and textile and sewing machines.
