There is a one task stack which allows you to change speed settings smoothly. gram itself when triggered with the suitable command. DESCRIPTION The IC is developed for automotive applications. The stepper motor driver is optimized to drive SAIA stepper motors, but is also verified with several bipolar stepper motors in the market. A stalled detection is fully integrated and does not need a shunt resistor. With a configuration bit it is possible to decide whether to stop the movement or not in case of a stalled situation.
