AUIR3330S
In pin and digital diagnostic
The IN has two functions. In normal working condition, the output follows the IN pin digital level. In latched fault
condition (over current and over temperature shutdown), the IN pin provides a digital feedback to the µ-processor.
This digital diagnostic gives a different frequency signal according to the fault type.
