8.3.7.3 CAN Bus Dominant Fault

The CAN bus dominant fault detects if the CAN bus is stuck in a permanent dominant (low) state. This fault is detected when the device detects a dominant on the bus for time ≥ tBUS_DOM. This fault is then indicated via the CANDOM flag shown on the nFAULT terminal.

This fault is only indicated on the nFAULT pin in Silent mode. This fault can also be seen on the RXD pin as a dominant pulse for a time ≥ tBUS_DOM.
