L9942 back EMF stall detection algorithm

Introduction
The L9942 is an integrated stepper motor driver for bipolar stepper motors used primarily in
automotive head lamp leveling. The L9942 can easily be used for other stepper motor type
operations as well. Anything from adaptive head lamp leveling and HVAC blend door
actuator control to EGR valve and throttle control applications can take advantage of the
features found in the L9942.
In each of these applications, stall detection is desired to d
