28 Video STSPIN820, silent, high-precision all-in-one advanced motor driver ST, a pioneer in the field of motor and motion control, offers a wide range of motor drivers covering the requirements of brushed DC motors, stepper motors and brushless DC motors over an extensive range of voltage and current ratings. Our line-up of STSPIN motor drivers embeds all the functions needed to drive motors efficiently and with the highest accuracy, and include an advanced motion profile generator to relieve the host microcontroller, while ensuring robustness and reliability thanks to a comprehensive set of protection and diagnostic features. The STSPIN820 Stepper Motor Driver integrates control logic and a low R DS(ON) power stage and is housed in a very small QFN 4x4mm package. 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 and offers protection features like overcurrent, overtemperature and short-circuit protection. Able to work in a wide voltage range from 7 to 45V with a current level up to 1.5A, meeting the operating conditions of most industrial applications, the STSPIN820 achieves a resolution of up to 256 microsteps, guaranteeing very precise positioning as well as smooth and silent motion. In a miniaturized 4 x 4mm QFN package, the STSPIN820 monolithic stepper motor driver integrates the expertise and excellence of ST's motor drivers for integration nd performance. IDEAL FOR Bipolar stepper motors in applications from 7 to 45V such as: • CCTV, security and dome cameras • 3D printers • Textile and sewing machines • ATM and cash handling machines • Medical equipment • Industrial 2D printers • Office and home automation • Points of sale (POS) • Robotics KEY FEATURES & BENEFITS • Extreme position accuracy and motion smoothness: with up to 1/256 microsteps per full step • Integration of the PWM control and the power stage made by 500mΩ R DS(ON) MOSFETs guarantees one of the best performance-cost trade-offs • Easy step-clock and direction interface • 7 to 45V operating voltage for wide range of applications • Maximum reliability: UVLO, over-current and thermal protections • Compact 4 x 4mm QFN makes it the smallest integrated microstepping driver with these ratings ^
