FAQ

What is the maximum operating voltage for the LIN SBC?

The LIN SBC can handle a supply voltage up to 40 V, with an operating voltage range of 5 V to 28 V.

How does the device handle wake-up from sleep mode?

The device supports remote wake-up via the LIN bus. A falling edge followed by a dominant bus level triggers a wake-up request, switching the IC to fail-safe mode.
