|---|---|
| 1 | All gate driver outputs are disabled as soon as a short circuit failure is detected. |
| 0 | The short circuit event will only be indicated through the NIRQ pin. |
Bits 6:3 – SCFLT [6:3]
(Submit Feedback)Short Circuit Filter Time bits: The filter time needs to be configured according to Current Limitation Detection/Short Circuit Detection Time. The filter time starts after the edge blanking time (tEG_Blank) has expired and a VDS voltage larger than VSCREF has been detected. If the sensed voltage drops below the detection threshold during the filter time, the filter timer will be reset and will restart when another short circuit event occurs.
