Mode of Operation
3. Fail-safe Mode
• LIN bus
• EN pin
• WAKE pin
• VS undervoltage
The internal termination between pin LIN and pin V
current (typical 10 µA) between pin LIN and pin V
activated independently from the actual level on pin LIN or WAKE.
At system power-up or after a wake-up event, the device automatically switches to
fail-safe mode. It switches the INH pin to a high state, to the V
exceeds 5V. LIN communication is switched off. The microcontroller of the application
will then confirm normal mode by setting the EN pin to high.
