Application note
Software filter algorithm for open-load
detection on the L9935 device
Introduction
This document describes a software algorithm used for detecting an open-load condition.
The algorithm refers to the L9935 two-phase stepper motor driver. The algorithm identifies
the open-load failure within the failure class and filters out occurrences of false open-load
failures.
