STMicroelectronics Stepper Motor Driver IC 16-Pin Surface Mount QFN Package 1.3A Output Current STSPIN220

STMicroelectronics STSPIN220 Stepper Motor Driver IC in a compact 16-pin QFN surface mount package offers advanced motor control with high efficiency and precision. Designed for stepper motors, the STSPIN220 integrates both control logic and a power stage with low RDS(on), enabling smooth motor operation and optimized energy use.

The integrated controller features PWM current regulation with programmable off-time and supports microstepping resolutions up to 1/256th step, allowing fine movement control for applications requiring high accuracy. The device operates across a broad supply voltage range from 1.8V to 10V, making it ideal for battery-operated and low-voltage motor driver applications.

With a maximum output current capacity of 1.3 Arms, the driver ensures ample power delivery for small to medium stepper motors. It includes a comprehensive protection set including non-dissipative overcurrent, thermal shutdown, and short-circuit protection to safeguard both the device and motor during abnormal conditions.

The STSPIN220 is housed in a small QFN 3.15 x 3.15 x 0.98 mm package, suitable for applications with space constraints. Its surface mount footprint supports automated PCB assembly and compact system design.
