3.11.3.1

Pattern wake-up (default)

Figure 18. Wake-up behavior according to LIN ISO 17987-4/2016

3.11.3.2

Status change wake-up - Recessive-to-dominant

Normal wake-up can occur when the LIN transceiver was set in standby mode while LIN was in recessive (high)

state. A dominant level at LIN for tLINBUS switches the device to active mode.

3.11.3.3

Status change wake-up - Dominant-to-recessive

If the LIN transceiver was set in standby mode while LIN was in dominant (low) state, recessive level at LIN for

tLINBUS, switches the device to active mode.

3.12.2

CAN transceiver supply

The two low drops out voltage regulators (V1 and V2) are able to supply the CAN FD transceiver when configured

as a 5 V LDO (see Table 6).

CAN FD supply is monitored, only in active mode, assuring the properly rail:
