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.

FEATURES
► Supply voltage range 9V to 16V
► Stalled recognition without additional shunts
