For automotive applications like headlights levelling/swivelling, climate flaps adjustments or Head-up Display (HUD) positioning, a stepper motor is often the ideal and cost-effective choice for your design. Thanks to its operation mode, a stepper motor runs through a discrete number of positions, so it can then be driven to move and hold at one of these steps back and forth.

ST offers the best-in-class solutions for stepper motor control, providing integrated drivers for bipolar two-phase stepper motors, capable of current controlled micro-stepping and embedding diagnostic features. Furthermore our SPC5 family 32-bit MCUs are the perfect choice together with voltage regulators and ESD protections to complete your billing of materials and start with application prototyping.
