Product Description
STMicroelectronics STSPIN820 is a high-performance stepper motor driver IC integrating control logic and power stage within a compact 24-pin TFQFPN package (4.1 mm x 4.1 mm x 1.1 mm). Designed for precise motor control with output current up to 1.5 Arms, it supports operating voltages from 7 V up to 45 V, making it suitable for a wide range of stepper motors.
Featuring PWM current control with programmable fixed OFF times and microstepping resolution up to 1/256th of a step, the STSPIN820 enables smooth and accurate motor positioning. This IC includes comprehensive protection mechanisms such as overcurrent, short-circuit, overtemperature, undervoltage lockout, and thermal shutdown, enhancing system reliability and safety.
The device can enter a low power standby mode to reduce power consumption during inactivity.
This motor driver IC is ideal for industrial automation, robotics, instrumentation, and embedded systems that require efficient, precise stepper motor control. Applications include 3D printers, CNC machines, and other motion control systems.
Integrated PWM current control with fixed OFF time and microstepping up to 1/256th of step. Low RDSon power stage with typical value of 1 Ω combining high side and low side MOSFETs for efficiency. Comprehensive protection set including overcurrent, thermal shutdown, and undervoltage lockout.
Compact 24-pin TFQFPN surface mount package for compact PCB designs. Wide operating temperature range from -40°C to +150°C ensures robust operation in harsh environments. Low supply current of 3 mA reduces energy consumption in standby.
RoHS compliant, ensuring environmental safety and regulatory compliance.
