STMicroelectronics’ STSPIN220 is a tiny, single-chip motor driver which combines low power consumption, a small form factor and outstanding performance.

Measuring just 3mm x 3mm, the STSPIN220 integrates both the logic and power functions required to drive small, battery-powered stepper motors. Operating at a resolution of 256 microsteps per step, it provides for extremely smooth motion and fine positional accuracy.

The power stage of the STSPIN220 features efficient integrated MOSFETs which minimise energy losses and heat dissipation.

• Operating-voltage range: 1.8V to 10V
• 0.4Ω combined high-side and low-side MOSFET on-resistance
